Re: My 1998 Olds 88 has been stalling and running rough.
Check and clean the IAC valve. Idle Control Valve. Use brake cleaner or carburater cleaner . Remove the duct work from the air filter assembly. It is located just inside . Run the engine at 1200 rpms and spray the valve. The valve can also be removed and cleaned.

flashing light most always means missfire. could even be crossed wires.to the plugs. you really need a code reader and find the trouble code . but in the mean time make sure the firing order is correct. good luck .gary
what about the maintenance of the car spark plug, wire,fuel filter, air filter , clean trottle body, then also try to idle engine and hit the MAF lightly if engine stall or run rough then the MAF is defect
when you say stalls, do you mean shut off of just get low on power?
my check engine light comes on and then oil press light come on and the car shuts off but the lights and music stayed on.
if its that the car needs oil and shuts down to protect itself but it will turn on minutes later.
if stalls periodically, shows check engine light and the car looses a bit of power, in the engine, :
1. your coolant may be having problems getting to the engine in the way it was met to get to the engine
2. the belt might be a bit off and that could be why you get the slipping feeling
3. your exhaust may be a bit clogged. or your engine may need cleaning
i had both problems my car shut off and my engine was slipping. my EXPENSIVE but great machanic found out it was my oil level and my coolant was rusty and not getting to the engine. now she drives like the original 97 olds 88
