Hi, I’ve been looking around, but can’t really find the advice or info I’m looking for. I recently bought an Audi A4 (the one specified in the title) and had to replace the clutch almost immediately after I bought it. So, I put the new clutch in, but when I went to test drive it I couldn’t rev the engine past 2k without the rpms dropping and the car losing almost all acceleration/power. The engine came on by this point so I checked for codes, and my car gave me two: P1426 and P1545. After examining the engine bay and looking for any sensors that might not be connected I figured out that I hadn’t reconnected my evap canister purge valve, which would explain P1426, which says something about tank ventilation stuck open. But P1545 is the one that is confusing me, because my throttle body seems to be working fine. My guess is that it’s something involving my intake. Maybe MAF? I could be wrong however, so if anyone has any advice on it please let me know. This is my only car and I really need a running vehicle.
