[QUOTE="tt335ci03cobra, post: 15533556, member: 68944"] Problem found! Now as tech savvy as I claim to be, this one is in the weeds and almost over my head. Soooo.... Don't shoot at me too much if this sounds impossible as I don't remember the names of certain parts but here goes. We had pulled the ac condenser from between the radiator and intercooler for spacing. The ac pump was still connected and kept trying to complete a loop/signal. It started to fail but unbeknownst to us. Slight weird symptoms krept in but we very rare. Fast forward 2 months and 1500 miles, the car has the spark plug like issues daily. After checking coils, plugs etc with testers, swapping, etc nothing. So Heath thinks back and remembers the last time he's ever seen anything like this. **This is where it's over my pay grade so I don't know the components or parts as well** Something had stressed a component in the timing assembly which operates on a "ring gear" iirc and a slot style groove which had worn those parts out from excessive movement. This lead to a system pulling/retarding timing to 5-6°... Intermittently... Additionally, because it was almost stalling/dying, it was cause slight clutch engagement signals which further mucked things and created worse drivability. (I'm sure I've butchered the diagnosed by now, use your knowledge to decipher my lack there of) So... Heath's ordering some billet pieces that can't fail as easy (it's 14 years old stuff anyways) and pulling the turbos off to get the timing cover off and fix it. Please comment and let me know if you have an odd issue, I'll run the symptoms by Heath and see if he has any ideas. Heres the best part... Heath puts the car on the dyno to test his theory. It baselines like 520whp when it had made 720whp before. Timing was 5-6°. He sets it for 20-24°. It goes to a realized 12° and runs perfectly, makes 700whp again... The guys insanely talented... I would never have found this. [/QUOTE]
