came out this morning after the car had sat un-run for about a day, and the car just starts missing! Could bad o2 sensors or melted wires cause this? Any help would be appreciated.
And its NOT plug wires from what i understand - just replaced those with the Thunder Racing OTVC kit, and no (i repeat NO) plug wires are touching headers or belts.

Thanks!

 

when i had a miss it was the distributor that needed replacing....
twice....
just an idea..

well unfortunately you will have to do some investigation. You will have to check spark to all cylinders. Then you need to do a leak down test on all cylinders if you don't find anything wrong with the spark test.
