I found a used cat and the guy wants $150 shipped. It has 150k miles and still wants a lot of money. Anyway, I reset the CEL and cleaned the MAF again while trying to decide to buy or not to buy the cat. So far I have driven 160 miles with no CEL. I also started using 93 octane gas. My daughter has been using 89 octane gas if that matters. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 |
