ok, from day one my af gauge new swings and says im running really lean. in an effort to fix or find this problem, i have replaced the following or had them checked to make sure they are fine:
new o2 sensor, twice
new fuel filter
new oem fuel pump
rewired the fuel pump
had the fpr checked
had the injectors check and ran cleaner
retapped the af gauge
datalogged my car and it said im lean and have knock
checked for a swing with a multimeter directly at the o2 sensor.
everything ive done has made no change and im out of idea. the gauge doesnt swing which is usually either a fuel problem or the o2 sensor. since the o2 sensor is new im leaning to a fuel problem. how can i check for this. i dont have a fuel pressure gauge or an egt gauge or and afc. if i have to get one of those 3, which should i get first, cash is low......
thanx for any help in advanced
