Hi nticherp, sorry i'm new here i don't know how to post here. here is my problem
i have a problem with my aveo 2008 salon Manual gear in idle mode if turn on A/C the engine will not increase the rpm i have change the throttle body and change the sparks also change the fuel pump also check there is no leak of air also when check it by the OBD there is not code and still same problem!! could you please advise for fix it? is this problem with the ECU unit? is there relationship between the ECU and increase the RPM? also i would like explain that when drive the car in cold everything is ok but when driving for 1 hour and put the gear to N the RPM will come to 200 then back to 800 sometimes make the A/C off.
thanks you in advance.
