no power unless i restart engine
I have a 97 z28 .new optispark ,iridium plugs ,racing wires,headers high flow cats,performance cat-back exhaust etc,etc.I just had engine rebuilt 3500 miles ago.Sometimes when i go for a spin i notice i have less power and exhaust is alot quieter.My car will usually be doing 80-85 on the freeway on rampWhen i get on it it seats you back and your seatandit is loud *** hell.When i have no power i am only doing 60-65 flooring it no power and no pull,i can't even burn my tires i power brake but the rpms just keep rising but wont spin tires.The only solution is to pull over and shut the engine off for a minute and restart car and it will be back to normal .I don't know how long this has been happening because i have only been having fun with it and driving it hard for the last 1000 miles.It doesnt always do this sometimes i can let the car warm ip for 5 minutes and it will smoke the tires immediatly, thensometimes i drive it around for an hour plenty of time to warm upand it still has no power.Theonly solution is to restart the car.Any help would be apreciated.Thankyou.

it might b the plugs u have,,, I bought the same thing then had some work down at a shop very well trusted for work on LT1 and LS1s and they replaced my plugs with ngks and when i found out i was a lil pissed off cause those iridium plugs aren't cheap 14 bucks a plug and the shop owner told me he would not put those plugs back in, he told me i would loss power and that those type of plugs do not well in LT motor since they r a hot plug and that I needed a cold plug,, but then again i could b wrong, i never had any probs with the plug nut i only ran them 4 about 2000 miles so with headers u should have no prob switching them out and seeing if that helps the shop owner told me that the ngks were the best for my motor and so i would say try ngks the cheap but if they fix the prob then it will b an easy fix,, anyways just my thoughts good luck..

[] is there any conditions you can associate with the car when this happens?? only cold, up hill around a corner, cars been on for 15 minutes or is it completely random?? could be when passing thru ufo zone
