Question about 1992 Buick Riviera

1 Answer

Car starts then stalls once the engine warms up.

My Riviera stalled while I was driving about 60 the other day. Now it will start and the engine will rev up, then, instead of idling, the car just stalls out. If I let it sit for a couple of hours or so, it will run for 5 or 10 minutes before it stalls, but it runs really rough. What could this possibly be?

    I have a 1990 Buick Riviera with the same problem. Stalled going about 60 on the interstate, and now the temp gauge maxes out, the car stalls, and will not start unless cranked hard. the idle is also extremely high. tried replacing the IAC and it worked for one drive but stalled again when the car door was slammed.

    Driving along and engine just quits, check engine light comes on. Floored throttle pedal to keep engine chugging along, went about 2 miles and then it kicked back in and is running fine now. This has happened several times in the last three months. Need solution.....
    Ignition coil or timing gears and belts....what might it be?????

You need new timing belt and gears. Buicks gears are made of plastic, and become a big glob. Nothing for the timing belt to grab onto.

My 1988 buick century stall,s after driving. engine warm,s up.won,t start right after stalling.start,s after sitting 10 or 15 minutes

Possibly an ignition module or crank sensor problem. These are the two most common stalling electronics that will cause a stall when they get warm/hot and will then continue to operate once cooled down

Having trouble with engine killing or running rough even after it's warm.

not for sure but it could be your cam sensor. if the check engine light is on then take it to a parts store and they can run a scan and give you more information

Chances are your distributor cap, it may have carbon buildup ad is acting like a jumper wire to other spark plugs or it may have a very fine crack in it with carbon buildup shorting two plugs together. It's best to have it replaced, they don't cost that much and it's easy.

1986 Riviera random Stalling at idle

These are also notorious for the crankshaft position sensor (CPS) failing intermittently and causing this same issue.Some of the vibration dampers (crankshaft pulley) were also known for the reluctor rings that trigger the CPS for coming loose and causing a timing issue and/or destroying CPS.Be sure to clean the mounting surfaces for module of any dirt or corrosion and apply some good dielectric grease to surfaces. Check the engine grounds and battery + connections for clean and tight as well.These are some other notorious problems with these. Good luck and hope this helps! Rate me please.
