P0300, P0304, P1174, CEL ON ! I need some help resetting the CEL. I would like to reset the CEL and drive it again for a while and see if the CEL comes back. Can I just disconnect the battery for 5 minutes to reset the CEL? If the CEL comes back, I would like to change the coil pack first as I have a spare. Check the rubber boot after the MAF for leak. Then change the spark plugs, then O2 sensor last. Does this sound logical? Thanks. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 |
