Ok, so i got a diagnostic done cause my check engine light was on after i changed my test pipe out for the highflow cat by 42 draft. the code is telling me my MAF is bad, so my question is when i get my new MAF this week, after installing it do i need to disconnect the battery to reset ecu or do i just put it in and start it up and will the light be gone lol?

 

It should be gone almost immidiately.

 

ok thanks ill let you know how it goes.
