Engine rough

[GPD151]

Got in my car yesterday, a '10, 2SS/RS with 43K miles on 6spd. Started up and immediately sounded like a chopper "womp womp womp" on what sounded like 2 cylinders only. Towed to dealership today, prob end of week before they get to it. Any idea what would cause this? Tried starting it 3 times same result. All dash lights on. It was parked outside overnight since I shut it off, and it hasn't been ran hard at all since last year at the track, probably 10K flawless miles since then, just highway miles for the most part. All plug wires are attached to the coil packs and to the plug too. Any ideas?

GPD, This just reminded me of a similar situation with mine... My car did the same exact thing. I poped the hood and noticed my plug came off of my throttle body somehow.... I put it back on and it ran good but my CEL was on..... just an FYI

[E.T.]

That blows. Good luck, hopefully it's an easy fix.

It could be many things. Mine was exactly like this when it broke a valve spring. My car is a daily driver and had about 36k miles, when just cruising down the hiway the spring broke.

Good luck, hope it is something simple.
