Basically put the car in first gear start releasing the clutch and the rpms drop down like it wants to stall. I had idle issues specially with the AC on so went ahead and cleaned the throttle body and maf sensor and my idle did improve. A few days later it seems like that issues is coming back a bit any thoughts? I've searched online and it seems it might me the Tps.. Anybody know how I can test it? Any help would be appreciated.
