I own a 1991 Cavalier VL 2.2L with 205000km on the odometer. Recently the car has acquired a stalling problem. It started to stall intermittantly, but it would seem the problem has been getting worse. When it stalls, I have no warning. The check engine light also does not come on. Since the stalling problem first occurred, I have noticed somewhat erratic idling. One day when I start it, it will idle very low, the next quite high under similar conditions.
Originally, I replaced the idle air control valve, spark plugs, pcv valve, and air filter. After installing a new fuel filter the car now revs excessively high to the point where I no longer feel comfortable driving it (approx. 2000rpm idle).
Any ideas where I should start?
