Thanks Dean,
I might try to do a swap out with one that works to see if it changes anything.
just a bit tight on the $ right now after the 300 for the new high flow cats and looking at possibly pulling transmission to check flexplate. But Then again, sounds like I will need a MAF anyway and if it solves it then it is well spent.
Could a lean backfire be that loud? would it change pitch with RPM? From low click/sputter sound to high clacking at higher RPM? Asking because I have never heard one before.
That is a new thought though. Thanks.
John
