SR20det idle problem. Please help!!!!!!!!!!
Ive searched online for this and there are endless threads about it and the main suspect is a dirty or bad iacv or tps went bad, but not in my case. When I am driving the car it is fine, that motor has bolt on mods and has been tuned (power fc). I have swapped and cleaned the iacv, check voltages for the maf, tps and other things along that line. When i drive and come to a stop the car wants to die, so i have to keep feathering the idle to keep it on. Now I did notice one day just from dicking around that when I let off the gas coming to a stop if I turn the fuel pump off(wired to a switch), the car will idle fine. Then of course once it runs out of fuel i turn it back on and it idles fine. I have also swapped out the fpr with a good one just to see, and still the same.
any input?
And no I have not hooked a fuel guage to it yet at idle to see the pressure but I plan to do so this week. Just wondering if anyone has had problems with this.
