I just went out to lunch and before I went i took the jb+ out. (using proper procedure, of course) Drove to in-n-out and CEL disappeared, and car started pulling normally and no sputter. Basically running how it's supposed to.
When I was installing it I disconnected the battery and then installed it as opposed to waiting 15min with the hood open for the ecu to fall asleep. (Jb website says either way is fine) maybe that's my problem?
