Today's "stalling" question...

[jsta6]

I know it has been asked before, and I have read the archives, but I still wanted to ask.

If I drive my car like a normal, sane person, I have no problems.

If I drive it like I stole it, hauling ass on the highway and boosting a lot, I have a problem.

When I come to a stop, with the car in "drive", it will buck and stall. When I re-start it and drive it, the car is fine, until I stop again.

Putting the car in neutral or park fixes the problem.

No codes. Check engine light doesn't come on after I start the car. (it does work).

I have 009's, reds 93 chip, smc, adj fpr new fuel pump and filter, LS1 MAF. TPS is correct.

I am getting a new O2 sensor this weekend to possibly address some low O2 readings at WOT.

I don't "think" I have a vacuum leak. All the hoses are basically new, they visually look fine. I do have vacuum brakes. BUT, my FP drops kind of fast after I turn the car off, I heard this could be a vacuum leak.

I hope that is enough information...

When my engine is cold and running at idle in P], my boost gauge will show almost 19 pounds of vaccum and when I put the car in gear it will show a very steady 14 pounds vaccum.

I often though if I every had a vaccum leak those reading would change.

Does the car act like it doesn't want to stop? If so, then maybe your torque converter is not unlocking.
