high idle after maf install
Recently bought a c-tune with autothority maf from someone to replace my a-tune
The car runs but instantly revs up to 2000rpm and slowly crawls up from there. The only vacuum lines I have messed with are the 2 on the fuel rail and one on the bypass valve. The car ran an idled great prior to the upgrade.
I noticed that the 80lb injectors didn't look like they would fit with the clips so I left them off as people apparently have done so in the past with other injectors.
Screwing the idle adjustment screw all the way in changes nothing, as does blocking off the icv hose. The throttle plate is closed all the way and the tps resistances check out fine.
I guess what I want to ask is are there any other possibilities to try before I blow $130 on my second tps in 2 years
