Default Help...throwing codes after exhaust install
Hi. Several months ago I installed an aftermarket MAF and cold air intake. Everything worked great. A couple weeks ago I installed a Borla exhaust. I disconnected the battery after both to ensure the PCM relearned.

I noticed right away after the exhaust install my idle increased and within a couple days the check engine light appeared with the PCM code indicating lean fuel rail (I forget the exact codes at the moment).

I'm hoping I missed something simple. Any suggestions?

Thanks.
