My buddy Jmaxx93 just acquired a 90 GTU. Problems will be described as no power. Decent but possible power exists up until the 5-6K range where no power is available after. We read on here and found that it could be the 5th and 6th ports. Wired those puppies open(okay we used vice grips) and the power seemed somewhat the same. thought it could be a gutted cat, but when he went to emmissions he past like it was brand new. Truely we are stumped. Anyone else have problems similar. He thinks the car might now be missing(ignition) or a sticking injector. your thoughts

Does the CEL happen to come on when the power goes low?

 

CEL used to come on. Code 12. We rigged the sensor back a little and it got rid of the code. aside from that im clueless

 

double post..I was seeing if it was going into Limp Mode
