    The 02 sensor for european car bypass only affects hot starts, not cold ones.

    I have it unplugged.

    check the spark plug wire orientation! if 2 and 3 are backwards, it will definately bog, pop, make weird noises.

    also, are you sure that the plugs are hooked up to the right plugs? That causes backfiring popping and a shitty driving experience.:rofl:

    How did you Isolate the bad coil, I was running the car with all four coils in, but not necessarily bolted down, (so I could pull them off the spark plug. I didnt find a dead cyl (this was idling).

    Buttchug, I swapped in junkyard AFMs, and had no luck. I think I even bought an AFM off of a member with no luck.

    justin,

    This morning I got a cup of boiling water, and stuck my spare CLT sensor in it, with it connected to the wiring harness. and I had no luck in causing or finding any problems. I have a new CLT and a spare one off of a running engine. I have swapped em in and out with no luck.

    I did unplug the camshaft position sensor, and reset the computer. I was getting the same symptoms, however, the backfiring was much more rhytmic
    pop pop pop pop pop popop (not revving higher than 1500 RPMS, but holding it.)

    as opposed to camshaft sensor in.

    POP boggggggggg pop POp bogggggssss down back to idle. or dies.

    yo, Thanks everyone for your help. whoever has the winning discovery I have some spare VDO gauges I can distribute. :D

    Just thinking out loud here. From my experience with MSQ, if you don't have enough cold start enrichment the engine will run like crap for the first couple of minutes. Now if you had a failed coolant temp sensor on the M42 so that it read HOT all the time, the engine would be running way lean on cold start. Sorry if this has already been addressed in the thread.

    sounds alot like the cps, did you see my thread about the problem I was having? about sludge and dirt buildup on the cps? clean it with some carb cleaner.

    not sure if this helps, but SOMETIMES if it starts bogging down, and I floor it, the car Violently jerks between bogging, and actual ignition, like Sputtering of working and non-working.

    Im going to re-test my sensors, will report back. I dont understand how this can be happening there has got to be a bad signal somewhere.

    LEts assume I just encountered this problem, What series of tests would you conduct to try and pinpoint the problem, being fuel, or spark related?
