Hey guys. Been scouting these forms for months since I got my car last year. I'm in Alberta Canada but this seems to be the best forum for info.
Anyhow, I have a. 1989 r32 gtst with the rb20det, fmic, rb25 turbo, walbro 255, blitz intake and bov delete. It will not idle when warm. The car will stall coming to red lights after the rpm drop almost everytime. I have a brand new tps sensor in the car and I still get code 43 (tps code). So I'm wondering is this my issue? Does anyone have any idea what the voltage is supposed to be going into the tps? I have 5v at the 3 wire plug and 12v at the tps sensor it self. I set the tps to. 0.48 where it should be and still nothing. I watched the voltage go up smoothly with the throttle all the way to wot (car off, ignition on) it reads 4.08v.
My iicv will not help adjusting my idle either..
Also while I'm revving the car. I'll hold and maintain idle at 3k or 4k whatever I tried it at it sounds like a misfire Is also happening. I have brand new plugs in the car so I'm certain it's not that. It boosted fine last summer with no hesitation or missing, (haven't been able to drive it since because of winter here).
What do you all think it is? Clearly an issue at the tps or something.
Thank you all for the help on this, I hope to have this solved rather quick. I do plan to swap some Toyota echo coil packs in very shortly too, if anyone has some info on wiring that would be appreciated too!
