[QUOTE="upsidedownthinker, post: 462117, member: 25707"] I’m 99% certain they are good. spark plug 3 Was cross threaded (which is Bank 1 side) and I don’t believe it was changed last time. Cant say for certain. In the meantime Im hoping to use the fooler until I can rethread and replace that plug. If that’s not it, maybe it is actually the aftermarket cat. - that’s my thinking anyways. I’ll need to fix the plug thread for sure but what else would throw a code where using a fooler doesn’t ignore a legit issue? [/QUOTE]
