    We've replaced fuel pump and filter, egnition module, sparks plugs, coils, plug wires.

    I've had the same problem...the battery was replaced, the fuel pump checked, okay...the fluids were low, oil, water, and once filled it seemed to work, but after driving for hour or so, it started to miss again and it won't continue to run?

    The transmission fluid was low and we added more but put the wrong type of transmission fluid in so next we will drain and add the correct type...

    What next?

I have a 94 sts caddy and the mile/gal display on the DIC is all dashes. I have error codes to72, io34, no PCM data, no RPM display, no temp guage display, no fuel used display and others. When the motor is not running, the message ' stop engine ' This problem started quickly. I just replace a front wheel bearing and sensor and still there is no change. Anyone have an answer?

Have you checked that battery? it seems that it may need replace it might not be keeping a charge, the connectors to the battery could also possibly be corroded as well, which could caue connection problems, i had the sam problem with my old car and it turned out to just be the connection from the cables to the battery due to bolts needing to be tightend or corrosion.

94 3000gt problems

Could be such a multitude of things.Good news is for that problem 90% chance it is very minor but usually not cheap(small sensors cost a lot).You have to take it to an auto parts store for a FREE diagnostic check. Takes 5 min. and will tell you what sensor,ECU etc... is bad and would cause your particular problem.Spend your $ ONLY on what is causing your actual problem and if another part checks out bad but is causing no problem do not waste your $ on replacing it.BE WISE BEWARE and use common sense.

My 94 Cadillac eldorado is having a very bad serging problem in overdrive and in lower rpms in 3rd gear. What's wrong?

Had same problem on my 94 eldorado touring and it turned out I had bad ign coil. This sets a 41 code. Check codes for no cam ref signal. Sounds stupid but if one coil stops firing on only one cyl it sets that code. There are 4 coils and they run 2 of one end of ign module and two of other end.

94 VW Golf. Starts and runs sitting, drive it about 10 mins and it just dies and won't restart. Have changed Coil, wires, plugs, cranck shaft sensor. Fuel Pump/Filter?

a)When you go to restart it does it die right after restart?
b)Does it die after you put it in gear after restart?
c)Doesn't restart at all?
Not sure if you changed fuel pump? If you did eliminate it from cast of characters.

If a & c engine main relay or fuel pump
If b torque converter clutch solenoid

94 eldorado stalls

First impression is a MAP sensor. If you take the car to a service station or an auto parts store that features free diagnostic tests, I'm sure the MAP sensor fault will appear. Other cause could be the TPS which controls the idle at cold,warm, and AC operation settings. It's possible that you're stalling due to insufficient idle speed setting on the TPS.

94 jimmy will not run bad fuel pressure regulator?

Nothing wrong with the regulator. That is how it is supposed to work, it sounds normal.
I guess you will have to get to the spider to see what is wrong. Fuel delivery to the pot seems normal. Could be something to do with injector circuit, IDK. Sorry can't help more.
