I have now had the MAF and AOS replaced, yet the P1124 and P1126 codes have come back once or twice over the last few months and it comes back in minutes if I reset it now.
In the last few days the idle is rough 50% of the time, and with the AC on, when I push the clutch in the RPM drops to 700 before recovering and is just on the cusp of stalling, like letting off the clutch without enough gas. Additionally, every so often, particularly when I shut the car off I hear a hydraulic type compressor sound from in front of the passenger door. Lastly, I could swear that the car is lagging a split second between when I put my foot down and I get power, even at high RPM's.
Any thoughts on what this is? Fuel pump and air leak? I want to try and get an idea of the problem before I send it to the mechanic.
Thanks!
