i have some hesitation somewhere after 3500 rpms, i thought it was the ground wire of the battery so i grounded it to the strut and another to the tb. i thought it worked but it still hesitates after the rpm, but not all the time just more than it doesnt hesitate. i just am wondering what else it could be, my fifth and six portes are opening and closing, i know it cant be a vaccum leak cause i bought silicone vacuum lines and sealed them all. could it be timing or something with the msd i am running. i am so confused.

I know some people have had success splicing an additional ground on the ECU ground wires to cure 3800 sag. Test the ECU grounds (there are 6 of them) with a voltmeter. All should show -0- volts. If they don't maybe regrounding could fix your problem.

Are your secondaries working? Maybe they are clogged.
