Hey guys,
So I got a Silvia s13 sr20det and it hunts at idle.
The ecu is auto but has had the 5 shift conversion.
When I put in a manual ecu the rev counter doesn?t work and it misfires like a bitch. With the auto ecu it drives fine!
I tested the tps and that?s fine. Took the idle control valve out tested that and cleaned it, both solenoids moved when given 12volts. After putting everything back together clean with new gaskets I tried to adjust the idle control valve.
After unplugging the tps the engines idle went to about 2000 and wouldn?t drop, moving the idcv screw doesn?t make any difference what so ever.
I have order a new tps (just in case) but does anyone have any advice or thoughts??
Thanks!!!
