Have a strange sputter for roughly a week now.the car starts fine but only until it hits 5 lbs boost then it begins to miss heavily.figured it be a crank sensor.. but after replacing it the problem still exists.. read around more online and read an artical about the wires to the coil packs drying out and cracking.. inspected them.. and they were all corroded and the old rubber was brittle.. replaced all the wired re wrapped them and was certain they the problem was gone.. but it persists... If someone could provide some insite it would be greatly appreciate...thank you..

 

I had a similar problem a few years ago, turned out to be a loose hose clamp causing a boost leak, but only over 5 or so PSI. It's worth doing a boost leak test to at least eliminate that.

 

Thanky you brad.. I greatly appreciate the insite.
