More to this. Borrowed a friends Snap-On Modis scanner.. Seems that the LTFT are hitting 25% at part throttle and the STFT are arround 60%. Under WOT the front O2's are reading way lean... Funny the FP is dead steady at 58 PSI.. Wonder that since it is almost a 10 year old pump that it can't keep up anymore.

Tomorrow's project.. Ohm out the injectors, change the fuel filter again and do a volume test on the pump... yay...
