My car cuts off when I usually turn left. I had my spark plugs and wires done and my throttle body sensor done. Is it the hose pipes.

The car cranks but will not start. There is good fuel pressure but no spark. Thinking it could be the cam sensor or the throttle position sensor. Any other possible causes for the non start


Yes, check your plugs and wires... the throttle body and also check all of your vacuum hoses as well.

Pull one or more of your spark plugs and check to see if they are dry or damp with oil. This could be the result of bad rocker cover seal and or the seals around your spark plug chambers.

When attempting to start the car, if it turns over but no spark, then check plugs and wires, if you hear a clicking noise, then it could be a blown starter motor.

Engen problem and missing


Sir, your question is not very clear, but I will still try to post a solution here. Engine missing could be due to any problem in fuel system, ignition system, engine or ECM as well.

LOW ENGINE IDLE SPEED (Poor idling):
-Throttle body (do the cleaning and idle speed learning)
-A /C signal circuit
-Fuel pump control circuit
-Fuel pump
-Intake system
-P C V valve (clogged or open) and hose

ROUGH IDLING:
-Cylinder Compression
-Ignition system (Igniters, spark plugs, wiring harness)
-Spark plug fouled, gap too wide or too short. (1.00-1.1 mm)
-Fuel injector circuit
-E C M power source circuit
-Fuel pump control circuit
-Fuel pump (required pressure 44 psi - 49 psi)
-Throttle body (cleaning)
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Heated oxygen s ens or
-Mass air flow meter
-Idle hunting
-Throttle body
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Mass air flow meter

HESITATION/ POOR ACCELERATION:
-Fuel pump control circuit
-Fuel pump
-Spark plug
-Ignition system
-Fuel injector circuit
-E C M power source circuit
-Mass air flow meter
-Throttle body (do cleaning)
-Intake system
-Valve timing
-Cylinder Compression

Throttle position sensor


Should be on the left or right side of the throttle body opposite side of where the accelerator cable attaches.The TPS is a reostat (Variable resister) that is turned by the armature running through the throttle body.

Diagram of how to change spark plugs on a 2003 kia sorento


Hi there...i don't have room to post the complete diagrams here, but i can walk you through the steps. It's a little harder for a do it yourselfer than most cars, because the intake manifoild has to come off---one of the reasons a shop charges so much too...and a proper set of tools is very helpful. Your manual will have pictures, to help you identify the parts i describe here...ok u ready?

Take off the plastic engine cover and set aside. Don't lose the the little acorn nuts.

1. Remove the air intake hose connected to the throttle body.


2.

Remove the accelerator and cruise control cables.

3.

Remove the engine coolant hose and throttle body.

4.

Remove the P.C.V. hose and brake booster vacuum hoses.

5.

Disconnect the vacuum hose connections.

6. Remove the surge tank stay.

7.

Bleed off the pressure in the fuel pipe line to prevent the fuel from spilling & squirting you in the eye.

8.

Disconnect the connector from high pressure hose.

9. Remove the surge tank and gasket...be careful with gasket, you can reuse it.

11. Remove the delivery pipe with the fuel injector and the pressure regulator....
When the delivery pipe is removed, be careful not to drop an injector.

12.

Disconnect the wiring harness of the coolant sensor assembly.

13.

Remove the surge tank.

Ignition coils and ignition wires:
disconnect ignition coil harness connectors

disconnect ignition wires from ignition coils

remove hold down bolts from ignition coils

while gently twisting pull up and remove ignition coils

while gently twisting pull up and remove ignition wires

remove spark plugs (always check gap on new plugs, even if they say they are "pre-gapped" )

Install in reverse order, don't over torque anything and keep your work area clean. Now would be a good time for wire replacement too---depending on the mileage on your Kia

Do a good visual inspection of hoses, clamps, wires & pulleys while you have it "opened up" ---Good luck, thanks for using fixya and i hope you get many more trouble free miles out of your Sorento. =)

My '01 impala 3.4 v-6 flat spots when COLD, at around 20mph. the idle is ruff with random misfires. acceleration is overall poor. when HOT, most symptoms go away leaving only some slight acceleration...


depending on mileage, but possible tune-up could fix it. if already done then check ignition coil pack and ignition wires also spark plugs, check vacuum hoses for leaks or porous, last injectors clogged - use some techron fuel injector cleaner (wal-mart has them). Also get the throttle body and iac valve cleaned by throttle cleaner . Also this other possibilities are to be checked and confirmed.:---- Engine running rough or misfiring can be cause by the following:

1.Defective spark plugs
2.Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4.False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Manifold absolute pressure sensor
12.Mass Airflow Sensor
13.Idle air control valve

--------- This should help.Keep updated.Thanks.Helpmech.

1994 CHRYSLER LHS. CHANGED PLUGS, CHANGED WIRES,


Try removing air inlet hose at throttle body,and open plate up by turning throttle linkage slightly (engine off) and spray a shot ( second or 2 ) of WD-40 into throttle body, then try to start and see if it try's to start, or starts for a second then dies. If it does, you got a fuel delivery problem. Can you hear fuel pump hum at all in rerar of car when you turn key just to on position? (not start)
