scan the computer with a computer scanner just to see what it says. check your intake, I am thinking your mass air flow sensor is no good. it happened to my car where the rpm increases and decreases when the car is idle. Or it can be the IAC valve.

Idle speed for my volvo 850 too low. needs turning up slightly? when i start the car the idle revs are too low and car cuts out. but when its warmed up idling is fine.


Idol is controled by the computer. You need to run a diagnostic on the vehicle to determine what sensor is going bad. My best guess at this point is throttle position sensor or erg.

When engine starts it does not idle on the proper level. when it warms up it idles fine. I was told it might be my EGR valve. Is that a possibility?


yeah,. possible egr, but did you look at the IAC - Idle air control valve? -- controls the idle at cold engine temps by diverting the air from the manifold for heat to help warm up engine on cold start.

When I start my jaguar, it idols at a fast speed but then as it warms up it will idol fast then slow, fast and slow and keep doing so


if it is a v12, and at idle when warm if it goes up and down then you need to rebalance the throttles, they are off balance causing the idle to raise and drop.
set the butteryflys behind the air cleaners to 2 thousands of an inch using a fella guage and make sure the linkage arms from the pedestal in the middle of the engine are set the same (one is not longer than the other)
