hesitation at high boost...
I have a 94 3kgt and at high boost I have a really bad hesitation and I can't figure it out. Turbos both are fine... changed plugs (did use ac delco dbl plat though.) and wires aren't very old. I recently had a coil crack and I replaced it. the car sat for about 8 months and ran fine before I just can't seem to get this bug out of it! I've ran 3 injector/ fuel system cleaners through it, and I am due for an oil change. I'll try that next, but please any oferrings on similar problems and SOLUTIONS would be greatly appreciated. Thanx

Re: hesitation at high boost...
Need new spark plugs and gap them down to .32-.34 and get some NGK and might want to try to get 1step colder plugs.
good luck mahdi

Re: hesitation at high boost...
I would deff put copper plugs in there. Define "hi boost"

Re: hesitation at high boost...
you are getting spark blowout, switch to copper plugs and gap them lower as was said.

high boost = anything above 7 lbs.... What do you mean by copper plugs?

Re: hesitation at high boost...
a copper plug is a plug whose tip is copper. there are also platinum plugs and iridium plugs. but copper are the best for the boost application...and coincidentily coppers are the cheapest. (i'm talking about NGK plugs here).
