well ... weirdly the car came back 2 life. (the turbo motor) I turned the bac screw all the way out and then turned the idle screw in the back of the motor up hella. The car idled and I almost died. It was a 2500 rpm idle but it was an idle. I slowly dropped the idle screw down little by little, till now I have a 1000 rpm idle.
Its weird though, I hit the gas, and it revs up after a little bit of hesitation, but when the rpms drop back down, it goes to 500, then bounces up to 1000 and back down to 500 a couple times, backfires, and then goes back to holding idle at 1000. Any ideas? The tps is hard to set seeing how every time I change the idle, the warm setting of the TSP changes. Its super sensitive to keeping it at 1k ohm. Also I cant figure out what the screw that is by the pot does. It also changes the tps, but I dont know why or what its connected to. i have the bac screw back in, about half way with no change. I still cant figure out what the bac screw has to do with the idle. *shrugs* |
bac screw is the idle speed adjustment. if you're using anything else to set the idle speed something else is wrong.
i'd suggest getting a sub 1000rpm idle, and then recheck the timing, and start looking for vacuum leaks, and other things. |
playing with the bac screw does nothing for me. Maybe thats my issue? Why wouldnt it? Does it raise the idle when unscrewing it or screwing it in?
