  1. Anyone have any thoughts on my '04 Carrera? My May post above outlines some of my efforts to date. Since the Variable Timing Solenoid swap, I pulled the left bank chain tensioner, which seems to be functioning as it should. When I pulled the two green plugs on the camshafts, I noted the cam shafts lined up (suggestion timing is not out of whack). Car has been sitting in my garage for months and I'm completely out of ideas. Anyone? Help appreciated. I bought the Durametric and hooked it up. Showed the same misfires to left bank without any new codes.
  2. Could a bad Variable Timing Adjustment solenoid cause bank one to misfire on all cylinders and car not run? I have a 2004 996 C2 3.6 that I have been trying EVERYTHING to get running. The problem began during a cold start. Started fine, but while warming up, it started to run rough, then shut down. It cranks, and if I pump the gas it will run but only if I keep above 2k RPMs. Actron pocket OBD2 reader shows all P0300,301,302,303. No other actual codes, but monitors show misfire, catalyst, EVAP, 02 sensor, 02 heater. I swapped the Variable Lift solenoids (the other ones) early on in the troubleshooting. I've also changed out the plugs (again, though did it only 1000 miles ago), inspected all coils, searched for vacuum leaks, tightened down everything I messed with replacing AOS over Christmas break, new oil filler tube, new crankcase breather hose, intake manifold, new crankshaft sensor, cleaned MAF sensor, air cleaner and throttle body, swapped O2 sensors. I even made sure there was plenty of cranking amps and made sure there was gas and oil. I was at the end of my DIY rope, but this timing solenoid gives me new hope!!! Just swapped those Variable Timing solenoids. Still bank 1 not firing. Noticeably cooler than bank two exhaust manifold. Could there be a fuel issue that causes problems on only bank 1? Clogged fuel injectors just on that bank? Cam position sensor?
  3. The idea to remove the mufflers was key... until the mufflers ended up dangling from the PSE actuator lines. Fortunately, I was able to push the muffler on the driver side backward enough to get to #2 and forward enough to access #1. Work still in progress (#4 yet to go). Bracket is the biggest obstruction to accessing #4.
