Well I've been wrenching away at this thing for about six months now. Its been a lot of fun and the car runs real smooth except....... From tithe to time while cruising I would develop a slight hesitation at a steady cruise. Not much just real quick,about a 2-300 rpm drop. It started again a few days ago so I began trying to see what made it better or worse.
So I dropped it in to drive and it became a bit more pronounced. So then I slowed down to around 40mph and dropped in to 2nd in an attempt to load it a bit more and see if I could track down the conditions that would induce it. Then BOOM three consecutive back fires out the tailpipe and a tone of white smoke. I got it up and running again after a good look over and got it home with a code 34 & 41.
I changed out:
Cam sensor
Ignition module
Spark plugs
PCV
Now on to it. Only at WOT will I get white smoke. I followed behind the car and it is odorless. Removed the turbo and slic found no oil. Nor did I find any residue in the down pipe.
A compression test revealed a cylinders but #6 at 145-150 with number six reading about 135. And it looks visibly cleaner with a bore scope. I'm just wondering why its only at WOT when it smokes. All opinions are welcome.
