Sounds like throttle positioning sensor on side of throttle body or the gasket below tthe throttle body has gone bad.

Sometimes the gasket under the trottle body goes bad. spray carb cleaner at the base of the trottle (not down into it) body while the engine is running. if the idle changes your on the right track. its an easy gasket to change.

Idel to high starting, warm to low sometimes dies


What is to high? 2000RPM, 2500RPM? Also cold idle and start up idle and many other factors vary with make, model and type of engine, smaller engines in most cases need a high start up idle.

I have a 1999 2.2 s10 that is idling rough. It seams to have a little less power. Once warm seams to be fine? I think it was over heated? I cannot take the radiator cap off it is a sealed system.


The generic info for a rough idle on any vehicle is to check for a leak of some kind, fuel--egr--vacuum, something of that nature. Also,Clean the throttle body and idle air system.
How long since a tune-up? Anymore 02 sensors are part of a tune-up. Any applicable trouble codes?
There are two things I can think of that could be temp related. One is going from open loop control to closed loop control, the other could be coolant temp sensor issue? Don't replace anything unless your testing points in that direction.
There could be other issues?

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.

GIVE IT A FILTER CHANGE-AIR, FUEL. MAYBE PLUGS AND WIRES DEPENDING WHEN WAS THE LAST TIME. FUEL INJECTOR CLEANER, DON'T MESS WITH THE IDLE SCREW-THAT'S WHAT THE COMPUTER IS FOR.
