Hi,
Questions for the "tuners" out there...here are some readouts I got from my SVT while hot & idling in the garage...
Short term FT Bk 1 0.067 avg
Short term FT Bk 2 0.781 avg
Long term FT Bk 1 14.00 avg
Long term FT Bk 2 10.96 avg
Short term FT o2 Bk1 sensor 1 .523 avg
Short term FT o2 Bk1 sensor 2 .213 avg
Short term FT o2 Bk2 sensor 1 .322 avg
Short term FT o2 Bk2 sensor 2 .860 avg
The slight misfire I have been experiencing was coming and going at the time. It tends to go away the longer you let it idle but, comes right back when revved and returned to idle.
Fuel pressure at the injectors was averaging 47 psi.
Injector pulse voltage was 3.1 or .2 avg. both banks.
Now my question...is there something amiss (pun intended) with these readings, and if so, can a bad o2 sensor mess with fuel sufficiently (at idle) to cause a miss?
I went completely through the intakes, gaskets, IAC, EGR, TPS, TB, plug wires, plugs...everything...Heck, I even went into the plug holes and looked at the valves and pistons (can't tell you how I did that though ;~). There is no problem up top! I hate to think it's another fuel pump...but if it is it isn't acting the way the other two failures did...meaning I CAN accelerate hard up to 6+k with 1/8 of a tank and I seem to have pressure on the rail at 1/2 hr after shutdown...maybe longer...didn't check again.
Any thoughts? What other readings should I go after?
Thanks...Ed
