Check the idle air control. Looks similar to a C battery and its black on the throttle body. Pull it off clean it really really good with carburetor, or brake cleaner. It may be gummed up or stuck shut in its closed loop mode and that would choke the engine with gas.

THE IAC HAD HI-RESISTANCE. I REPLACED IAC & PUT A BOTTLE OF LUCAS INJECTOR CLEANER IN THE TANK. I STILL HAVE THE PROBLEM OF DIEING , NOT HOLDING AN IDLE ! WHAT ELSE CAN I CHECK ?

Have you checked for vacuum leaks? Get the gauge hooked up and get it to run at the lowest rpm you can. Come back with the rpm and vacuum it pulled

Nina, what do you mean by "it stays running??" A bad starter shouldn't cause it to stall. If the starter was the problem, then it simply wouldn't start. Also, what do you mean by "running rough??" Can you be a little more specific?

ok, for starters the 3.8 liter is a V6 not a V8. My 1989 Oldsmobile Delta 88 Royale Brougham, was having trouble staying running while I was driving, the following is what I did to get it back up and running. 1. replace spark plugs/wires, 2. Ignition control module, 3. coil pack, 4. mass air flow sensor, 5. 02 sensor, 6, air intake sensor. once I got these done, it fires up perfectly every time. if you do it right (autozone rewards program) you can get some free in store cash for use later, I put a cold air intake system on my car after all that.

I have a 1985 Delta 88 Royale. Just had the fuel and vacuum lines replaced. A good cleaning and tune up of the engine. Gutless on hills still. So all those major leaks are fixed. Still has small leak in the rear main. Nothing in my dash works but the gas gauge. But all the lights and blinkers works. Now however it stalls whenever in reverse, have to gun in drive or stalls, and it's idling hot than stalls. Idling very high. Also need to replace transmission mount. Any ideals?
