Unfortunately, i'm pretty frustrated...a borrowed AMM didn't solve my problem like i expected. It did however seem to make my car run much smoother.... i think i may buy a rebuilt one anyhow because the one i have may have never been replaced before and may be getting tired. Btw, his ohm value across pins 3 and 6 was in the 200ohm area. I didn't do any adjusting since the tamper plug is in place.
Here are the results that I observed on my air/fuel ratio gauge...
The thing cycles back and forth as it should, but only between lean and stoich... when I have the headlights on, the thing just seems to run lean mostly and hardly ever cycles... this is the same for cruising on the highway in 5th gear at 60mph with just a touch of throttle, the thing runs so lean and doesn't ever cycle unless i give it a bit more throttle. Does this sound normal? I haven't seen one of these things running properly so i dont know what to expect. When idling, as soon as i turn the headlights off, the gauge starts cycling regularly... is this because of my high-wattage headlights making the engine idle a touch slower?
So, what's next here? I am thinking i should order a new O2 sensor just to give it a shot since it's cheap and i will probably also get a new TPS because nothing seems to ever change when i floor it... but when i snap the throttle shut, it does go stoich and even one led of rich sometimes.
BTW, i do not have my APC in right now.. but i think it should still go rich even with base boost and WOT right?
Maybe my fuel pump is just tired? It is quite loud and hissy from the outside of the car... I am just getting a bit frustrated here..
I do have a recently installed fuel filter and have tried various FPRs.
