Hi everybody,
I have a gmc jimmy 00 and the problem is my car not accelerate smoothly it shift at 3000 rpm and some time the rpm go zero when this happen the car accelerate and stop then accelerate .
Can be from the camshaft sensor or crank shaft sensor?

 

I had the same issue a few years ago. It was the cam position sensor. If you don't know how to do it correctly it is best to have a shop do it. Oddly enough about a week later my distributor went south. So it could be either one.

 

My car also now hard to shift when I drive it
any one have idea about these problem?

 

Is your Jimmy a automatic or standard? And can yall help me learn how to make my own thread?

if you mean the transmission ? my jimmy is automatic
