Hello everyone,
I have a Chevrolet Vitara 2007 (Colombia - Latin America retail), in essential it is a Suzuki Sidekick. It has a G16B engine (1.6L@16V). I'm writing this post because I'm having some issues with my car when I turn on headlights or defrost. Sometimes when I did that the ECU can't regulate the R.P.M to ~800 and the revolutions fluctuate between 400 or 500 while the car is stopped (idle), other times the ECU can regulate the R.P.M without problem. I'm going crazy with this problem. I already clean and check the TB, I did special emphasis in the ISC valve. (This problem happen regularly)
Another issue with my car (probably it is related to the first problem) is when I am driving the car in the highway during 20 minutes in constant speed and when I have to stop because of a traffic light or traffic jam in the city... in that moment when the car is stopped (idle) or I'm not touching the accelerator and the car is in neutral gear (ISC is working), the R.P.M fluctuates between 400 and 500 again... And sometimes the car turn off abruptly. When it happens I turn off and turn on again the car and it goes to work properly again. (This problem happen 2 or 3 times per month)
What can I do to fix those problems? (FPR realted problem?, TPS calibration?, anything else?) Someone tell me about a bad diode in the headlights circuit but I haven't idea...
Thanks in advance.
