I have trouble w / RPM
My problem is when i change gear from first to second my rpm goes up then goes down after 1 or 2 seconds goes
normal then changing to 3 gear does the same thing thanks.
I would test your throttle position sensor for the proper resistance with a volt meter using ohms setting. You would have to research the resistance to ensure the readings you get are within the range required or check yours and then go to the parts house and ask them if you can check a new replacement.
