Check engine light is on. It is giving a code for the front camshaft sensor - which I replaced. I also cleaned the Idle control valve and replaced the air intake boots, due to them being dry rotted. I have not checked for vacuum leaks yet. Will do that tonight.


check also the throttle body to see if it's dirty. the cam sensor would not do that
