Help! Engine Misfire and lumpy ride. Error codes: P1067 and P1339

[rczorcrz]

Hi,

My RCZ stays in limp mode, with a very rough ride, engine light on and the fan stays on after the engine has stopped.

Plugged in the ODB and it threw up the two error codes (1067 and 1339). I've swapped around the ignition coils, but it is staying on the third cylinder.

Any help or advice would be greatly appreciated!

After replacing sparks, VVT solenoids and clearance of codes. The car was running fine until acceleration, where it kicked back into limp.

The 'lumpiness' is now gone, as are the misfires, however the diagnostic is now displaying P0171 (air-fuel mixture contains too much air and not enough fuel).

Anyone have any ideas?
