Hey all
I'm so lost with my car now I give up. On idle cold or hot it hunts but more worryingly it seems to be blowing spouts of air out of the air filter. I can turn the engine off and back on and it might stop.
I've checked all vacuum and boost pipes. Installed new coil packs, spark plugs, maf, temp sensor, uprated dv, n75 valve, hockey puck valve, vacuum jet pump, deleted the two valves at the front of the engine.
Only thing I can think of is the head gasket, but surly it would blow all the time every time.
Its AUM engine with vacuum at -0.3. It's got stage one remap on it, standard turbo and actuator.
Any help much appreciated.
Cheers
Si
