Locate you computer (right front kick panel) and tap on it with a pen while the car idles... Also flex it back and forth with your hands to see if the car runs rough or quits... You may need a new one.

SOURCE: 97 Camry Rough cold idle, weak accelleration and noisy exhaust

Lots of times the idle air control valve gets stuck on these engines. You can try cleaning it. Remove the air intake hose from the throttle body. Start the engine and spray throttle plate cleaner through the hole in the bottom on the throttle body. This will run the cleaner through the idle air control valve. make sure to keep the RPM's at about 2000 to 2500 throughout this procedure. You may need to install a new idle air control valve if it continues to happen.

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

How to adjust idle?


hot engine ?, cold or both,, EFI runs in 3 modes, cold ,warm and hot.

name it.

which engine option (displacement)??????



there is no idle adjust, that is the PCMs, job 100%, all the time.

Carbs are gone.

here is rule one for all EFI.

idle is the last thing to work correctly.

anything the causes a gross imbalance of engine power to engine load, under idle will cause , idle controls to fail.



low idling causes. (over 50 but, here ar basics)

1: AFR (air fuel mixture too lean) usually surges. (clogged or leaking injectors. or fuel pressure way to high)

2: air leaks, cause racing, so not that. (speed density car ,if is)

3: egr stuck open. low idle and misfire.

4: ISC stuck closed (IAC electric)

5: cam belt slipped, timing retarded, compression at 1/2 spec, and well, valve will bend soon....

6: CEL glowing running? can be in limphome, limp cancels Idle controls (in may cases) RTM read the FSM on DTCs.



if fails hot?, is hot = 180F temp or more? "thermometer time"

if not, the PCM goes , quite nuts.

!993 Explore 4.0l When I accele I feel a surge in power..


so you gave it a tune-up?

possible causes of of loss of power:BAD SPARK PLUGS AND OR WIRES AND OR DISTRIBUTOR CAP.

GASOLINE FILTER PLUGGED THUS CAUSING YOUR ENGINE TO HESITATE. "loosing power"

AMONG OTHERS BUT THESE ARE THE MOST COMMON.

maybe the engine is worn......old engines tend to loose pressure and they start eating the oil, and also start smoking real bad.

this one is another casue of power loss too.
