ok so i cleared all codes in my 99 2.3. only codes that pop up are #3 misfire and knock sensor. plug looks great on 3. not black or anything. very clean. so where do i go from here? new plugs,wires,cap and rotor. have been done. thanks!

 

What were the original codes that you got? What are the codes that you are getting now?

 

Original codes were a vtec selinod code. Egr

 

Not your interpretation of the codes, but the code number Pnnnn. We see lot's of misreads and misunderstanding.

good luck
