Fresh rebuilt s5 gtu wont idle.
I just bought my girlfriend's s5 gtu, 1990 ,no sunroof, red paint, black interior, and it has my s5 convertibles bbs rims.
OK so it starts fine first try every time but will not idle unless I unplug the AFM. I have switched out three different s5 AFMs, switched TBs with different s5 TPS, replaced the oxygen sensor and throws up every code when codes are checked. So I am thinking that the engine harness could be the culprit, I have found a few s5 engine harnesses on here, but I figured I would post this to get input from some more experienced rotary people.
Thanks for reading.
