Hey there again clubwrx! Before I get crap for starting a new thread, I'd like to go on the record and say that I looked through many forums searching for answers but I couldn't find much. Most of the threads died out and the thread starter never went back and explained what it was. Anyways...I was getting a code P0345 for my drivers side cam sensor. I replaced it yesterday and everything was good. Went and filled up my car, it was running perfectly.
I got home, pulled into my driveway and BAM...started idling super rough. I assumed I had a vacuum leak because I had the intercooler off to do the cam sensor and I figured I probably knocked a line off. After verifying that they were all good, I finally got my car to throw 3 codes: a P0011 (having to do with the right hand intake cam position being off) and a misfire for both cyls 1 and 3. Out of curiosity I started reading and found a lot of information about troublesome AVCS (Active valve control system) faults. I started monitoring cyl roughness on all 4 cyls, as well as ACVS input for both sides. To my surprise, the right was running about 59 DEGREES advanced, while the left side sat at 0 as it should. There were an insane amount of misfires on cyls 1&3.
I tried unplugging the solenoid, no change...I looked at the filter under the banjo bolt (I read that these are a common point of issue for the ACVS system) and it was damaged so I removed it. I also cleaned the cam sensor on the right side. The misfires stopped, and I took the car out....same thing. Dying at idle, misfiring, etc. I pulled codes and this time got the 2 misfire codes for 1&3, but the cam position code was gone. An interesting code popped up though...a po171- system extremely lean. This makes me think that MAYBE, just maybe, I have some sort of fuel blockage on the passenger side, and the ACVS is trying to compensate by advancing the timing extremely. I'd like some suggestions on what to do next troubleshooting wise. I was going to check my timing via a timing light but I honestly wasn't sure how due to the lack of spark plug wires...could I just use the #1 coil wire? Thanks in advance! And thank you for reading.
