Yeah went back to emissions again this morning & failed . Before I went back. I cleaned & regapped my plugs to .52, inspected my wires for cracks they're ok.Also, the guy who did my swap told me to try Guarantee Pass. Did what they said fill my tank up, drive til tank almost empty refill tank & go to emissions. My CO was lower .09 from .30 & my HC went up from 439 to 603.
Now what do you guys recommend to solve this issue?
Thanks
