98 Formula, Got the P1416 code Done cleared it several times through OBDII and it keeps coming back. Yes Ive already done the search to fix the issue. The thing is Im seeing 2 different parts #'s for the valve..

12565503 and 22048212

When I go to http://www.gmpartsdirect.com/ It pulls up Valve for both of them.. which is the correct one? or are they both correct?

Thanks!

One is for 98-99 and one is for 00-02 - I'd just get one from your local parts store. http://www.ls1tech.com/forums/showpo...3&postcount=20
