| | 04 GTO problems
OK, I've read alot of different post on here as a guest, before signing on, I have a '04 A4 that I bought sight unseen on the internet, good price, but not as I thought. It had long tubes, no cats, SLP loudmouth, K&N CAI, no tune, melted O2 wires. I removed the longtubes, replaced with JBA shorties, JBA high flow cats, left the SLP anf K&N, did wires, plugs, O2's,Intake gaskets, smoked intake, no leaks, fuel pressure 58 psi at idle, driving car at 55-65 lt fuel trims are @18, around 80 lt fuel trims are @8, stft are varing between +3, -3, randomly throws P0171,P0174 codes, tried different MAF, no change. I had to put in O2 sensor spacers in the rear sensors to get it barely thru inspection (voltage @.120), engine light came on during exit, Also traction control randomly turns itself off, usually after a long decell, Does it need a tune? Or what to look at next?
