If the problem you are having after the engine warms up and you put the transmission in gear and it quits, unplug the torgue converter (overdrive). If the engine runs fine after this, then change your transmission fluid and hook the torgue converter back up and she will run like a champ. I had the same problem.

Troubleshooting a rough idle


The "rough idle" symptom encompasses many systems in the vehicle, which must all be checked. Is the "Check Engine" light on? Have you had the codes read? (Codes can be read and interpreted on your Cadillac using the air conditioning controls, the procedure for which can be found online using any search engine.)

Generally, especially on a car as old as yours, you will most likely need a MAJOR TUNE-UP. You will need to check all of the following:
  • Condition of the fuel in the gas tank (especially if the car sat dormant for six months or more);
  • Operation of the idle air bypass (Idle Air Controller);
  • Cleanliness of the throttle body and its components;
  • Condition of the fuel delivery system, including the fuel filter, pressure regulator, electric fuel pump, and injectors (this is the most likely suspect here);
  • Condition of the coil packs or distributor cap and rotor (I don't remember which your car has);
  • Condition of the spark plug wires;
  • CONDITION OF THE SPARK PLUGS (obvious);
  • Operation of the ECU (or whatever you prefer to call the computer that controls your engine);
  • Presence of any vacuum leaks or cracks in the intake manifold.
START BY REPLACING YOUR FUEL FILTER, then check for proper fuel pressure at the fuel rail. Replace the pressure regulator as necessary and, if you are not getting enough fuel pressure, it is possible that rust and debris in your fuel tank has clogged the intake strainer and may have damaged your electric fuel pump. Once you have eliminated fuel delivery issues, continue by examining your ignition system (plugs, wires, etc.).

Best of luck to you!

2.8 engine Would start when cool, but stall after


89 cierra? It should be DIS ignition so you can't have the timing too high. You said it has fuel and spark. Fuel pressure and injection pulse. Does it try to start if you spray carb cleaner into it?

1992 Pontiac Grand PrixPower loss,erratic idle


spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]

Engine starts up and after 1-5 minutes the engine will stall


the ECM is located under the hood on the passenger side under the coolant resevrior. i think you should get some professional advise before replacing all those parts.
