Default boost problem?

i did a tune up on the ssei. it ran very good for about 70 miles. i was on the e-way when i noticed whenever i get the boost up to 0 it would start putting and jerking. i let off just a little so it goes just under 0 and its fine again. it seems to only happen when i get to 0 on the boost guage, or when i go to pass. i tried flooring it and it putted, jerked, then would be ok for a split second then putt, jerk, then ok. can anyone give me clue as to where the problem might be?

seeing that you said you tuned it up...I would suspect improper plug gaping or wire problem first..Did it do this prior to the tune up??

Could the belt be slipping?

Had the same thing happen to me. Mine was an ignition problem.

Me and a buddy just went through a similar problem (granted it was a Porsche) and like con10der said, check out your plug gaps. If they're just barely close enough after a little bit when the resistance rises it'll become just barely too far. Also like he said, check the wires. We had to build my buddies ourself but after spending a few minutes trying to figure out why one of the wires wasen't sending juice I started thinking about how many defective wires go out every day.

I'll third the motion. Ignition. Even too close a gap can cause this. It has nothing to do with boost. I bet if you had a scantool on there, your O2 would be reading normal until it starts. Then it'll go rich for the unburnt fuel from the lack of spark.
