Hi guys new to the forum, created my account specifically for help:
I have a first edition (2008) Challenger Srt8 that just hit 50k miles. About 3 weeks ago it started misfiring in cylinder 1. It also began having issues starting: some days it would start perfect, other days it sounded like it wasn't getting enough fuel despite the fact you can hear the fuel pump perfectly running.
So I changed all of the spark plugs, new coils twice, still misfiring. Did a compression test and its like a brand new engine at 270 all around. I caved in and took it to my local stealership who deemed it wasn't the ECU or fuel injectors. They then preceded to say they'd need another $400 to go internal to find out what was wrong.
They supposedly were supposed to open the valve cover (did another compression test and leak down test) but the master tech went on to assume it was the camshaft falling apart and not letting cylinder 1 valve open/close. So currently my buddy at his shop is putting an srt8 max cam from inertia in (after dealership tried to charge $4k for a stock replacement) and want to know input to make sure that's what it is. Currently he's taking the engine out and soon the camshaft. But I'd hate to hear the news that it isn't fact that, and is much worse. Below is an idea of whats going on with it.
Currently in 2nd gear and 4th (5 spd auto) it bogs and shakes violently. At wot it kind of chirps out at top RPM; but that is it. Anything above 70 MPH right now cruising causes the check engine light to constantly ding with a misfire. I've never had this issue before and am so confused and worried. If anybody has insight into this it would be much appreciated. I've also reset codes via battery and then my tuner, both times the misfire returned.
