Ok, well I got a new tps put on, and tried to adjust it as best I could with a volt meter, and now the car runs well and idles good but backfires on decell around 3k, horribly, any ideas? I dont have the little light thing and I dont feel like making one, can someone tell me what ohm resistance it should have at idle? right now the tps has 1.70 ohms on the 20k scale on my dvom, any lower twords 1 and the car starts hittin fuel cut as far as I can tell and starts idling at like 200 rpm's and wanting to die... any suggestions, my exhaust and neighabors cant take much more of this backfiring.
