    I cut my mufflers off and drove my truck and within 5 miles my service engine soon light came on. I took it to autozone and it's saying that my MAF sensor is messed up. Is this due to no back pressure from mufflers? I've cleaned the MAF and it's still on. Thanks for any help!

    did you clean the MAF after the light or before it came on, did you use actual MAF cleaner?

    Also year/make/model would help some since there are differeing issues with different model generations. Also agreed with did you use maf cleaner etc? since the MAF is very very sensative.
