I have been getting a high RPM miss ever since I spilled coolant all over the front of my motor. I am replacing the e-water pump with a stocker so I might as well address the opti while I'm in there. Can I just replace the cap & rotor or does the whole opti need to be replaced

 

I just replaced the cap and rotor.like a year ago,and so far no problems

 

IMHO never ever replace just the cap and rotor. If you are going to have it apart replace the whole thing with a new gm piece. Don't buy parts store reman crap either.

Jason will ship you one for @ $235 complete.

 

How do I contact this "Jason" ?

 

Heaven forbid I put his contact info up, since hes not a sponsor.

His name has floated around forever on here though, Ill pm you.

 

Remove your Opti, open it up and take a look inside to see what is wrong. Normally, you'll be able to see the problem (loose rotor, coolant, Etc). If it was the high or low resolution pulses (optical sensor), you would be getting a code.

OK I'll check when I dig into it, thanks for the help guys.
