So I've got a p0420 code on my truck and I'm about to register my truck in oregon next month (it's got washington registration now), I could just renew in WA but since I live in oregon I'd prefer to have it registered here. I've had a p0420 code for a little while now but I've been strapped for cash since I'm a student working part time. The catalytic converter that's in there now was installed about 3 years ago, it's a magnaflow(never buying their garbage again...) and I haven't got any fuel pressure issues, plugs look good, compression is good, cat doesn't rattle, all I can think of as the reason for its failure is because it's an aftermarket part and not oe.
All that aside, I've got enough money saved up to register my truck next month and I'd really hate to have to blow that money on a new cat. I've done a little reading on cleaners that supposedly help you pass emissions but I'm not really convinced. My truck can run on e85 so I was wondering if it may help to fill the tank with that and clear the code before the test. Anybody know?
