Okay, about 14 weeks ago my Rx7 was running good until the LT8 wiring harness came in contact with the exhaust and melted the wires to the point were the car was hesitating an misfiring so I just put it in the garage and ordered a new wiring harness. I finally got the new harness, hooked it up, and started the car but now I have alot of white/grey smoke coming out of the exhaust. Now when I first turn the car on and let it idle its abit more smokey than what it ues to be but when I get on the throttle it gets really bad even at idle now. When I took it out for a test run it would only boost about 5psi then it felt like a fuel cut. Any suggestions?
