Ive been chasing a Gremlin in my car now for a few weeks now
It's a missfire when car is idling (VX LS1). I would drive the car around without a hitch, come up to a stop, then every so often it would get a small missfire. It doesnt create a code, it drops rpm about 50 then stall saver kicks in with some timing and it goes back to idle normal again.
This happens once every 30 secs or so. The more I load the motor up electrically (fan, blower, high beems etc), the more often it misses (batt voltage is lower)
I'm thinking along the lines of maybe a coil/module problem?
Is there any PID I can log that will tell me if this problem is happening on the same cylinder everytime?
Anyone with thoughts as to what this problem is?
