PO103 MAF Input Too High...
...Meaning voltage was too excessive for an extended period of time on the MAF signal circuit.
Mods: VF39 (ported/polished), STi IC, UTEC Delta, SPT intake, protuned, TXS TBE...
I have been having issues for the last few weeks and we been trying to figure out the problem... Basically, anytime I get into boost the above error happens. When it happens the car stutters and shuts off. Usually followed by the IGN fuse blowing. Not fun when on the highway... I've talked to some people including my tuner and we have a few ideas. The tuner P&L thinks the UTEC is pulling too much voltage. Someone else thinks maybe the MAF is getting condensation... The dealer thinks the MAF is OK...
A turbo: Exhaust gasses go into the turbocharger and spin it, witchcraft happens, and you go faster.
