Version 6 STI Running Rich Serious Over Fuelling
Hi Guys,
My V6 is running super rich, barely idles and pops and bangs. And throws fuel out the exhaust.
The car had been left up idle for a few months but drove perfect.. until I locked the diffs for traction on the snow and ice at which point it started to run rough. Practically impossible to start at times.
I know the MAF sensor are a weak point on these models but wondering if there is anyway of testing these prior to purchasing one?
I slaved in the original ECU with same result as the Apexi PFC.
i have checked the resistance on the Lambda sensor and thats ok.
Threw a set of known good leads and coil pack with nil fix.
The hand controller says that the ignition timing is a 21-23 degrees on cranking...what should it be?
Air Flow voltage is 1050 mV static with ignition on and 1270 mV on cranking...what should it be?
02 sensor shows 0.02V static and at cranking.
Any help would be much appreciated. Thank you in advance.

None of the above. Injectors show I'm at 49.7% at idle...any ideas please?
The car runs but is poring fuel out of the exhaust. My next concern is I want to avoid washing the cylinder bores and fuel oil contamination. Anyone else have this problem.
Thanks for the replies.

no probs glad to be of help make sure you change the oil, with that much fuel running through her you will of mixed it for sure, easy way to test is see if the oil smells of petrol, mine did and caught fire with just a cig lighter
