Ls3 misfire
Ls3 misfire Good afternoon,
I’ve got a g body with an ls3, tsp cam, ported heads and TREMEC magnum. It’s run by a Holley terminator x max. I drove the car 3( miles this morning with no issue and on my way home it started to misfire. It’s a single misfire when cruising. It’s random and without rhyme or reason. The tach will drop when it misfires. Cruising along at 65-75 mph and it will just hit once and then resume as normal. Smooth under acceleration. Any ideas? Thank you.
