Paul that is exactly the way the BMW did, it would go away and no problem for awhile and then you couldn't keep it from doing it, park it and go back.and no problem. Eventually it started putting the car in limp mode as it progressed until..... My advice would be to install Ben's TB now while his is on the jacks. That way you can drive it a few days, not just around the block and see if the problem recurs. Drove everyone nuts finding the solution because it came.and went, even thought it was the tranny at one point... 2 cents.
I'll put his TB on this weekend and drive it like that for a week. That may tell me everything, or nothing. :cryin: But I agree that it's worth doing.
Oh, but when the car is running correctly now, it runs AWESOME. And still has some more in it with a retune, I bet.
If you drive it for a week and you don't get the lag......buy a TB. PS: Yes more there after retune, with the changes its way off........again.
I probably will... though this year I've gone MONTHS with no symptoms, then it will crop back up. One week won't tell me anything, really. Unless it DOES do it with the new TB... then that tells me it's not the TB.
