Help! To much fuel!

Darkside180sx · Sep 30th, 2004, 01:01 PM

i have just completed the sr swap into my 91 240sx. But i have one problem every time i start the it it runs fine for about 3 mins and then it starts missing. Almost like its getting to much fuel. So i cut it off and take out the spark plugs.(gaped at .030) The spark plugs are soaked with gas and the the top of the pistons are soaked too. I have checked my lines going to the fuel rail and fuel preasure regulator and they are all correct. Any ideas would be greatly appreciated.

Thanks,
Ryan

I'm not totally sure on this one, but you may want to check your MAF, and try to gap the plugs a little more. (say .035-.036??).

borrow someones air/fuel gauge or buy one and see what the heck is goin on with the readings..... or get an Apexi SAFC and you can adjust the settings yourself.....

I figured it out... It was my safc II...the signal wire from the maf sensor was wired in wrong to the safc II...so therefor the ecu wasnt getting a signal and went into pig rich cause it wasnt getting a signal.
