Does it seem to run rough or just idle too low? These vehicles are common for low idles problems.

It seems to run rough
Expert:  Dan replied 1 year ago.

I would start by replacing the spark plugs and cleaning the throttle body. This is something you can do for around $30 or will cost around $150 to have done at a shop. Let me know how it goes or if you have more questions, thanks.

Spark plugs are new what about the cams shaft sensor how can I check that what should I see on a ohm meter
Expert:  Dan replied 1 year ago.

Camshaft position sensor would cause check engine light to come on and cannot be checked with ohm meter. Next thing to do would be to run some seafoam through engine incase you have carbon buildup on valves. Suck some into intake, let sit over night, then in the morning run in low gear at high rpm to burn out any carbon deposits. Let me know if that helps or if you have more questions, thanks.
