rough idle and light hesitation at take off, I changed plugs, wires and coil for cylinder 1&4. check engine light is off and has no codes. Anybody have an idea as to what is causing the problem

 

Might clean the throttle body and IAC valve. An Internet search will find posts on how to do this. Engine is a 5SFE model.

Make sure EGR valve is not slightly stuck open at idle.

Other areas are MAP sensor, cracked, lose or damaged vacuum lines.

 

does this model fit to any Camry?

 

thanks I will try that next and see if it helps
