Hesitation at high RPM's

+1 I thought by now the codes would be on the thread, why take the circuitousness hard way when you can get some clues as to where to start looking?

Tommy, no dis intended, in fact you're right in the hood and yeah it's been Noah's Ark. I always heard AZ would do free code reads but I never had to run the test. The other poster might be right spark plugs could be a great guess. Let me know if you need something, I can't lift but I can guide you through a lot of jobs including the plug tubes and plugs if necessary and I have a great set of tools including many of the Porsche specialty items, a Bentley manual and hours of wrench time on 1998 986.

PS Whose wrenching on it? Avoid Cantech unless you like paying 125% more than any job should cost.
