Idle is too high

Had a mechanic work on changing blown head gasket. now when i drive it feels like throttle sticks until you press on gas and release quickly to bring it to a fast idle. sometimes it revs up and down when warm?

SOURCE: idling high

are you using aircon? if yes observe if it beahaves OK if the aircon is OFF. Then if you turn the aircon ON does it go up? if so, you may have no freon on the system because the engine does not have a load and the aircon system is idle upping your engine.

SOURCE: 1995 Toyota Previa idles too fast when engine is warm

check to see if there is any carbon on the throttle body where the butterfly contacts it. also clean the " business end" of the idle air valve to make sure it's not being held open slightly.

SOURCE: grinding sound on pressing clutch in at high revs

The grinding sound may be a throw out bearing or the pilot bearing. The sticking throttle problem sounds like a linkage or cable binding up from possibly damage due to the impact from the accident.

Chevy Malibu 2001 with 89,000 miles idling too high during park


Back to the mechanic - sounds like either an IAC motor or TPS sensor is the problem, but also could be the throttle cable (sticking leaving the throttle not fully closed).

I have a 1991 talon eagle turns over when the gas is to the floor and wont say idling also when driving and coming to a stop it dies whats wrong


you could have a high fuel pressure problem and when holding the throttle all the way to the floor you put the system in flood mode which shuts off the injectors to burn off excess fuel in the engine.and when you release the throttle the system returns to normal.when driving you could be using the fuel that is being over supplied at the speed your driving.also the egr valve could be stuck open causing the engine to stall at idle.something to check out.

Firstly, i am experiencing a lot of top ups on oil (1 pint/week). My car smokes a lot and the smoke is white and blueish like. My exhaust is so black and oil greasy residue and some oil is leaking through...


your idle problem is because your carb is missing somelines such as vacuum etc.
the reason your top up is increasing is because your car is burning oil hence the white/blue smoke.
you need your head gaskets changed and also get your mechanic to take a look at your O-rings (piston rings)

In my 2000 Saturn SL1 I am experiencing very high idle (2000 rpm warm - higher cold). I have cleaned the throttle body and the idle air control valve with no improvement. What next, replace the idle air...


You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.
