    The EGR valve when faulty idles rough, and the rpms jump when in idle. This is NOT the symptoms. idles smooth, Bucks when engine warmed & driving

You have verified you have fuel pressure when it won't start? because what you describe is more like loss of fuel press not loss of spark, also have you run a code test on this to see if any ignition system codes pop up in memory? go to the link below for code test using the check engine light blinks out to read codes. also 40 PSI is low fuel pressure.

    car drives nice for 2 miles aprox. Then when i stop & restart & start driving is when bucking, stalling starts. The check engine light only comes on when bucking starts. My mechanic replaced the above parts because his troubleshooter scanner listed those items as FAILED. He replaced parts, cleared codes but problem persists. Yesterday the engine would not turn over, let it sit an HOUR and it MAY start, Jumped the car and it started right away.( jumped car because ran battery down trying to start the caddy)

    Had it back to mechanic. Used a new fuel pressure guage. Pressure at idle was 42psi, revved was at 52psi. He checked the wiring harness and found no faults. He got an update for his scanner and showed NO PROBLEMS on ECM. Checked with the closest caddy dealer (100 miles away) they do not have the flight recorder. On a suggestion from another person, mechanic is checking to see if the battery has a dead cell. He says that may cause improper codes to be thrown at scanner. Any other idea's?

  • jack_love Jun 04, 2010

    BTW was caddy mechanic who suggested battery cell. He also recommended checking for vacum leaks around intake manifold, He also said it could be an "appled" distributor gears. To my knowledge, which isnt much, the ign mod & coils replace the distributor dont they?

    THIS COULD BE THE PROBLEM, BUT WOULD NEED TO BE THERE AND CHECK IT MYSELF, WHAT CODES LEAD HIME TO BELIEVE IT IS THE COILS AND IGNITION, THIS IS A DEALER? THIS CAR HAS NO DISTRIBUTOR.

You have a plugged or a non working EGR valve. The EGR relay, Solenoid also can effect thisif at fault.. Press the heat and ac buttons at the same time to pull up the fault codes stored in the PCM

1997 vw jetta stalling when raining


The problem in the Jetta could very well be with the ignition coil. I had the same problem for a long time and tried the usual replacing plugs, wires, etc, but nothing seemed to work.

It ended up being the ignition coil which over time, managed to sustain very small cracks. Even a small amount of moisture would cause all sorts of problems.

I replaced the ignition coil and had no problems after that.
