Still no CEL. Great! P0420 has not come back ON. (Replaced MAF with used one with 90k miles and cleaned it with CRC cleaner) P0130 has not re-appeared also. (Replaced 238k mile two O2 sensors) (direct replacements from Advance) I am happy and it's ready for emissions testing and tag. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 Last edited by bazar01; 08-20-2014 at 03:13 PM.
