Possible fuel delivery problem, fuel pump, fuel line, clogged fuel filter, leaking injectors or injector O-rings, faulty pressure regulator etc. Check your fuel pressure.

    I am not familiar with 99 version but if you have multiple misfire check you cables or not sure if that model has a distributer but check your cables or coils

My 99 camry 4cyl, has a rough idle and sounds like a misfiring when accelerating when in gear. Any answers to what it could be?


You could sure be running on 3 pistons. Check spark plugs by removing one HT lead at a time with engine idling. One that's dead will not alter your idle speed when disconected. Replace bad plug and check the same cylinder again. If OK fine. If not check whether you are getting a spark to that plug and rectify. If you have both power and a good spark but still without power the check engine - valves and pistons.

1996 Honda Accord Rough Idle Even After tune up performed Changed spark plugs, distributor cap and rotor wheel along with all spark plug wires, changed fuel filter, air filter, spent $150 on fuel injector...


Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

I have a 99 accord that lacks power when I hit a hill. It runs fine and gets good mileage but I have to downshift from 5th to 4th on minor hills. Check engine light is off.


howdy, there are a few things on your 99 Accord that could cause that problem. usually all will eventually turn on the check engine light in time. make sure your check engine light is working when the key is first turned to run.

* a partially clogged catalytic converter.
* faulty O2 Sensor (Bank 1 Sensor1).
* low fuel pressure caused by a bad fuel pump, clogged fuel filter(in the tank) or a bad fuel pressure regulator on the injector rail.
*bad ignition switch which can cause intermittent stalls.

now i don't know which engine you have, (i'm guessing a 4cyl.) there were two 2.3L- 4cyl. engines (F23A1 & F23A4) and a 3.0 V6. but if you also have a rough idle or low idle miss, a jumped timing belt can also causing loss of power.

if you know anyone with a scanner that reads the computer datastream, see what the O2 Sensor (Bank 1 Sensor1) is doing & look at fuel trim readings. Also check backpressure on the converter where that O2 Sensor is screwed in.

please let me know if i have helped, totally confused or scared you to death! Good Luck!
