alright guys, this is just to make sure i am on the right track.
First, today while i was driving and on boost, almost like boost cut, i lost power. But was still running rough(driveable).
I thought piping came off at first. Second, not sure if something is seriously wrong, but my vacuum hose to FPR have intermitten vac pressure.
I noticed this by my Fuel Pressure gauge not moving. Staying at the same pressure with both vac connected and disconnected.
but it would come back.
Finally, thinking it was a boost leak(not probable because recent dyno showed strong boost and it held)but it wasnt.
So, I just did my usual test by disconnecting each plug wires while car is running rough, and found that the #3 cylinder had no spark!
but my #1 had spark. only on #3. So after reading up on the diagram of the iginition system. I dont think its the transistor or ecu.
The problem would be #3 spark coil. I drove the car all the way home just fine. just not that powerful or smooth idle.
does this sound right or am I missing something?
