My 93 camry 3.0L will surge and stall when I put it in drive or reverse. The surging idle goes from 700 to 1500rpm. It runs fine when in neutral or park. Please help.

mercury sable This sort of sounds like some technical issue.. try to fix it yourself. It's easy, my mom tried

the compressor that pumps up the air suspension does make a horrid noise, and if you can turn it off, like I could in my crown vic, just long enough to see if that is indeed the compressor making the noise you hear, then try that. My switch was located in the trunk.

Get the fuel mapping sensor looked at. what type of car is it?

It's usually a carburetor, or clogged fuel injectors. Other times the fuel filter is clogged.

check with your dealer vechicle may need to have the electric throttle learn procedure done if battery has died or been disconnected

Check your Idle Air Control Valve (IACV)

put a throttle position sensor on the throttle boby this should fix the problem!

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
