need help ?
something went wrong.
parked vehicle for the night, next morning vehicle has these codes: P0300, P0301, P0302, P0304, P0171, P0506 plus went into limp mode.
googled codes but before I get crazy and tearing things apart. Does anyone see a dominant code that code cause all ?
misfires, to lean and idle air control to code all at once, one of these had to go first & triggered the rest. right...

and how do I reset the limp mode ?

Look for an air leak after the MAF. It may be a failed vacuum hose, an intake hose or the intercooler. The best way to test is with a boost leak tester with pressurized air. You can make one yourself. Depending on where you live, it may have been an animal eating through a hose overnight. Limp mode will only stop after the repairs needed to stop the codes are complete and the car is either driven enough to clear the light or it is manually reset via coding.
