odd misfire So I'm working on a vehicle and was hoping to have some input
its a full bolt on car with ls6 heads/cam/intake. Here's the situation;
The car drives great and has lots of pep, but at idle when hooked to a tech 2 i detect a little misfire. The SES light never comes on and I only notice the slight 'Miss" when i'm at a dead stop idling. My first thought was, am I just overexag. Cam "Lope"... but then again it's only an ls6 cam.. nothing big.
I have new plugs, wires and even changed the coil packs around. The injectors have been cleaned recently and a compression test was done. everything checks out fine... the misfire is mainly shown on cyl#4 with one or two coming from #7 and #6
any ideas, I'm stumped

I got the same problem no ses light but small random misfires at idle .I did change the stock wires (Ohm at 720) with GMPP red wires (Ohm at 300) and it slowed the misfire count down but didn't stop it. Its been over a year now, i gave up on it
