After you install mods on you car like a cold air intake, or a new exhaust system, do you need to disconnect the battery to reset the computer? Does it make a difference if you don't?

Thanks

Yes, you should.

It WILL make a difference, but with any mod, the computer doesn't know how to react until 5-6 starts after the battery is disconnected - so the difference sneaks up on you.

If you don't disconnect, it takes a long time for the computer to adapt, and you may get some errors no one will be able to explain, until you start going down the list . ..
