Question about 1994 Chevrolet Camaro

3 Answers

My camaro is idling at 3k rpm in park

When I start the car it idles at 3k rpms and never comes down below that no matter how long I drive it. If I unplug a vacuum hose on top of the manifold the idle becomes very rough. What should I be looking for on this? I thought maybe a sensor or vacuum hose was bad but not really sure because I have never actually worked on this car before.

If you are not the original owner then the previous owner may have set the idle high, if you take off the throttle body there should be a little screw that will set the idle by keeping the intake valve open more if you unscrew it then the idle rpm will lower

Listen for a hissing sound you could have a vacum leak . spray carb cleaner around the thodle body and the intake to see if you have a bad gasket or just needs to be tighting.also check the choke and throdle pationing sensor it could be stuck open!

Okay next to the vacuum that runs to the booster is another smaller on. It has no line and when my truck is idle it runs at 3k rpms and when I shift it drops and jerks to 1200 rpms


Have you tried plugging the small opening to see if the rpm comes down? Also look for a vacumn hose that has come loose and is lying out of sight.

Idle too fast?


Check for vacuum leak at the base of the throttle body. Also check all vacuum line and for loose connection points

Engine high rev at stop and slowly goes to idle speed.


I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck
