For the first couple minutes of driving the car will start to buck when accelerating, then it will drive normally. I recently changed the spark plugs because it was doing this and the plugs were covered in soot and the first couple threads had a bit of oil on them. It drove perfectly right after I changed the plugs. The car smokes like a chimney on startup and after boosting, but the color of the smoke is different. On startup it's blue and after boosting it looks white.

Could it possibly be oil leaking from the valve stem seals and soaking the plugs causing them to not fire right for the first couple minutes, then after driving they dry off? Grasping at air here... :dunno:

First, I would start off by looking at This Link. Then if that doesn't seem to be ringing a bell:

Did you happen to crack one of the connectors to the coil packs when replacing the spark plugs? If they're damaged in ANY way, it can cause a whole slew of ignition problems.

I've already tried another ECU and nothing changed, I didn't see any cracks in the coil packs either.

I just drove it around after letting it sit for a day and a half and it drove fine. Maybe the below freezing temps had something to do with it. :dunno:
