Tarago 96 - revving high in park or neatural approx 2200 rpm normally 900rpm Change Drive (auto) revs still high approx 1400rpm No engine light on, seems no other problems. What would be the cause? Oxygen sensor??
Too much air can be caused by binding throttle cable/linkage try disconnecting it. Next would be cold air bypass that lets extra air in for cold weather and initial startup. It would be located on the throttle body
with 2 wires that operate a solenoid. These become gummed up and can be cleaned with carburetor cleaner. Next the EGR valve on the intake manifold could be leaking. Check for cracks or leaks and sometimes the base it mounts to is plastic and wears out. Lastly is the dreaded vacuum leak. There are so many places and hoses to check that I would need to see for myself. The larger hose can go to power booster for brakes. Intake manifold gasket can also leak due to worn gasket.

You either have an intake manifold leak, a defective trottle position sensor or a stuck idle speed control valve.

start by pulling hose off egr valve see if idles smoother almost instantly

it is your idle sensor which needs to be replaced and this is right up on the firewall. it is right next to the manifold.
SOURCE: Oil light in 1999 Toyota camry comes on when idling.
bad to worn out oil pump or excessive oil passage clearances that allowing more oil to pass thru them at a lower pressure due to the bigger opening. It can be a sign of an emminant engine failure due to oil starvation.

TAKE THE AIR CLEANER OFF THE INLET MANIFOLD LOOK DOWN THE THROAT AND SEE WHERE THE BUTTERFLY IS SITTING YOU WILL SEE WHERE YOU ADJUST THE IDLE,YOU ADJUST THE IDLE SPEED BY BY TURNING THE STOP PLATE ADJUSTING SCREW TO INCREASE RPM SCREW IN TO DECREASE RPM SCREW OUT__ NOW !!!BE SURE TO ....LOCK THE ADJUSTING SCREW WITH THE LOCKNUT I THINK THAT IS WHERE YOU TROUBLE WILL BE ...
