I met jcassity yesterday and he referred me to this forum I have a 1988 turbo coupe that I have converted to 5 SPD car ran good then it started stumbling when it starts to build boost right around 3000 rpms need help
Could be blowing spark out but need more details
Well car ran good with the auto n it then trans went out put 5pd n ran good but couldnt put foot n it runs good out of boost just cleaned egr and put LB computer back n it its getting worse don't no wat u mean by blowing spark out this is my 1st turbo car
When my XR-7 (2.3t) did that it was a burned spark plug wire that would only arc at high RPMs. It idled fine, but would stumble when boosting. Threw on a new set of wires and it was fine.
