I bought my car from a friend, at first there was no problem on it but i noticed that the engine is kicking sometimes, then it becomes often, if I'm on my cruise control it will suddenly disable. Then last night i was traveling with my family, the engine kicks then the RPM shut, the engine is still running steadily but i noticed that the gas pedal is not accurately responsive. Then i park the car and restart it, the rpm returns back. Im able to drive it for almost 100km then it happened again. I restart it and return back to normal, i decided to switch off the AC and got home. I hope . someone could help.
