runs fine until It warms up
I've been having this problem with my lt1.. 1992, it runs fine until it gets to operating temp. Then it starts to miss and kinda buck. Had check engine codes. They were for the intake air temp sensor.I replaced that and the throttle position sensor and it still happens. It's not over heating and everything else looks normal. 93,000 miles on it. Just replaced both o2 sensors and it still happens. I'm done now and I'm bringing it to a shop on Fri. I'll let you guys know what it was when I find out. The opti spark distributer was shot.... After paying $850.00, it runs great!!!
