Question about 1992 Honda Prelude

1 Answer

My 92 prelude (95 h22a motor) has had alot of mods to it. catback exhaust , cool air intake, and most important,series 2.0 air fuel ratio converter. Just after purchasing car, i messed up and tried adjusting vtec control while car was in motion. 1200 dollars later the vtec control has been rewired(properly), got a new radiator, tune-up,etc etc. However my car still doesnt idle right, fluctuates from 720 to 920 rpm and sometimes wont start after driving for awhile. I have two after factory fans 12'' installed and when they kick in the cars idle drops down. I have had the alternator checked and it is good. Any ideas?

The idel even on a stock car will vary if the TPS is bad or miss adjusted. The TPS has two circuirts. one is the varible with the position and the other is the on idel and off idel. working with the wires disconected find the idel on and off with an OHM meter. set the position with the idel closeed and as soon as its moved it's off recheck to make sure it does'nt hang and then disconnect the battery and go thought idel relearen knowing the the idel off works ( start the car with the pedel down and then keep the r's at 2000 pluse steady for 2 minutes, then slowqly idel down till it idels on it's own and then let it idel, do this with everything on , AC, Brake,Headlights and everthing eles. Let it idel for a minute and then shut it off) Now it's set unless you've done somehting to upset the computer.

I NEED replace head gaske


Hi there:Removal and InstallationExcept Accord V-6


The cylinder head temperature must be below 100 degrees F (38 degrees C); allow the engine to cool several hours if the car has been recently driven. Turn the crankshaft pulley so that the number one piston is at Top Dead Center (TDC) of the compression stroke.

  1. Disconnect the battery ground cable.
  2. Drain the cooling system.
  3. Remove the air cleaner and intake duct assembly.
  4. Label and remove the brake booster, PCV and charcoal canister vacuum hoses from the intake manifold.
  5. Remove the engine ground cable from the cylinder head or valve cover.
  6. Relieve the fuel pressure using the proper procedure. Disconnect the fuel lines.
  7. Disconnect the accelerator cable at the throttle body or carburetor. On automatic transaxle vehicles, also disconnect the throttle control cable.
  8. Disconnect and tag all the wire harnesses and vacuum hoses from the cylinder head, intake manifold and throttle body/carburetor. Disconnect the spark plug wires, then position them aside.
  9. Disconnect the upper radiator hose. Remove the heater hoses from the cylinder head.
  10. If equipped, remove the cruise control actuator. Do not disconnect the cable; move the actuator out of the work area with the cable attached.
  11. Remove accessory drive belts.
  12. Disconnect the inlet hose from the power steering pump and plug the hose immediately to prevent fluid leakage. Remove the power steering pump from the cylinder head and position it aside.

When the power steering hose is disconnected, the fluid will flow out. Cover the alternator with a shop towel to prevent the fluid from leaking into it.

  1. If the alternator is mounted to the cylinder head, remove it.
  2. Remove the power steering and alternator brackets if they are mounted on the cylinder head.
  3. Remove the distributor. Be sure to scribe a line relating the position of the distributor to the engine for easy installation.
  4. If equipped, remove the cylinder sensor next to the distributor.
  5. Remove the valve cover.
  6. Remove the timing belt.

Do not crimp or bend the timing belt.

  1. Remove the exhaust header pipe nuts and the header pipe bracket (if equipped). Pull the pipe away from the exhaust manifold.
  2. If equipped, remove the EGR crossover and air suction pipes.
  3. On Accords through 1989 and Preludes through 1991, the cylinder head can be removed with the intake and exhaust manifolds either still attached or removed. On other models, the manifolds should be removed first.
  4. On some engines, it will be necessary to remove the camshaft holders, camshafts and rocker arms to access the cylinder head bolts. If so, refer to the proper procedures in this section.
  5. Remove the cylinder head bolts in sequence (take notice of any bolt holes occupied by longer bolts). Failure to follow this procedure may cause the head to warp.
    1. On 1984-89 Accords and 1984-91 Preludes, work from the ends toward the center. Loosen each bolt about 1 / 2 turn each time and make several passes to release the tension evenly.
    2. On 1990-95 Accords and 1992-95 Preludes, follow the loosening sequence shown in the illustrations. Loosen each bolt about 1/3 turn each time. Repeat the sequence until all bolts are loosened.

3_5_2012_9_19_50_pm.gif
Fig. 1: Bolt loosening sequence on 1990-93 Accords and 1992-95 Preludes with 2.2L engines

24. Remove the cylinder head. The head may resist removal, even with the bolts out. Tap the edge of the head with a plastic or rubber mallet; lift the head straight up to remove it.
  1. Remove the cylinder head gasket and clean the mating surfaces.
  1. If applicable, remove the intake and exhaust manifolds from the cylinder head.

To install:
  1. Install a new head gasket on the engine, making certain it is positioned correctly. The cylinder head dowel pins and the oil jet must be in place. Refer to the illustrations if necessary.
  2. Install the head. Lower it straight down onto the block, aligning it correctly.
  3. Apply clean engine oil to the bolt threads and the contact face of the bolt head. Install the head bolts finger-tight.
  4. On all models except 1988-89 DOHC Prelude and 1992-95 Preludes with 2.3L and VTEC engines, tighten the head bolts following sequence A. On 1988-89 DOHC Preludes, use sequence B. Use sequence C on 1992-95 Preludes with 2.3L and VTEC engines.
    1. On 1984-89 Accords and 1984-91 Preludes, tighten the bolts in two passes. The first pass should bring the bolts to about 22 ft. lbs. (30 Nm). On the second pass, tighten the bolts to their final torque of 49 ft. lbs. (68 Nm).
    2. On 1990-93 Accords, tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 78 ft. lbs. (108 Nm).
    3. On 1994-95 Accords and 1992-95 Preludes, the bolts are also tightened in three passes. Tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 72 ft. lbs. (100 Nm).

  1. If applicable, assemble the intake and exhaust manifolds to the head. Use new gaskets.
  2. If applicable, install the cam, rockers and camshaft holders.
  3. If equipped, install the EGR crossover and air suction pipes.
  4. Connect the exhaust pipe to the manifold using new nuts.
  5. Install the timing belt.
  6. Install the valve cover.
  7. Install the cylinder sensor (if equipped) and the distributor.
  8. If applicable, install the alternator.
  9. Install the power steering pump, then connect the inlet hose to the pump.
  10. Install the accessory drive belts. Adjust the belt tensions.
  11. Install the heater hoses.
  12. Install the cruise control actuator if it was removed.
  13. Connect the spark plug wires. Connect all the wire harnesses and vacuum hoses to the cylinder head, intake manifold and throttle body/carburetor.
  14. Connect the throttle control cable and/or accelerator cable at the throttle body.
  15. Connect the fuel lines.
  16. Install the brake booster, PCV and charcoal canister vacuum hoses.
  17. Install the air cleaner and intake duct.
  18. Refill the engine coolant. It is recommended that the engine oil be changed whenever a cylinder head is removed.
  19. Connect the negative battery cable.
  20. Start the engine, allowing it to idle. Bleed the cooling system. Check the work area carefully for any signs of fluid leakage or any indication of the timing belt rubbing or slapping the covers

I have a code reader and the code is P0171 P0174 System too lean. what makes the system too lean?


P0171 - Fuel Injection System Too Lean Bank 1
Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection

P0174 - Fuel Injection System Too Lean Bank 2
Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection

What Causes These Codes: Fuel injection system does not operate properly. The amount of mixture ratio compensation is too large. (The mixture ratio is too rich.) The Powertrain Control Module (PCM) monitors the engine Air/Fuel mixture ratio, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The PCM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios. In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the PCM judges the condition as the fuel injection system malfunction and light up the engine light. The codes is usually set when there is an intake leak after the air flow meter, before replacing any parts check for loose or broken hoses and intake gasket leak. On Ford some models dirty air filter, and dirty or faulty air flow sensor are the cause of the problem.

Does a h22 motor just drop in a 91 accord , is there anything i should know


You will need to know if is a h22a or h22a4. The h22a has the kind of fuel injectors that you'll need with your current set up. Also, you'll need the ECU. If you are putting a 95 or newer h22a in the car then you'll need a P13ecu to run the Vtec. You'll also need to run power to the vtec solenoid on the h22. If you're using a 96 or new Prelude engine it will be OBD2, your current wiring is OBD1. Your best bet is to get a 92 thru 95 H22a only.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

Engine cut out at 4500 to 5500 rpm while you are driving.


Check your fuel pressure, and see if your exhaust is flowing right. If exhaust is not flowing good then your catalytic converter is stopping up. Low fuel pressure would be because eather fuel filter, or fuel pump. Also check your air intake filter and your fuel ratio.

How much more hp would i get with headers and new system


Headers and a freer flowing exhasut just by itself won't gain you alot of power,maybe 20 horsepower.What is needed is a freer flowing intake and fuel supply along with a better ignition curve to fully take advantage of the freer flowing exhaust.If running fuel injection,you would need a performance chip for the ECU/PCM,to really take advantage of the exhaust system.If running a carburetor,the jets would beed to be increased in size slightly,and a performance curve programmed into the distributor.Think of an engine as a huge iron lung,air in,air out.When you make modifications or improvements to increase the amount of air flow overall,air IN is as important as air OUT.They both need to be adressed is what i'm saying,to take full advantage of any mods.Providing the intake,fuel and ignition are addressed along with the headers and exhaust,expect a good 50 horsepower gain overall (V 8) if not more.Higher gains will require a more radical camshaft,and some driveability will be sacrificed there.
