Well dig around and let us know what you find. Maybe someone else can chime in here with better advice.

A rough idle isn't going to kill anything, but a log of it might help with diagnosis. I do wonder if it's something to do with fuel pump or fuel delivery somewhere. How's the DI ECU grounding connections?

check all cold side piping and make sure everything is tight. Make sure the MAP sensor is correct (plugged in/right one) and make sure your MAF sensor is plugged in as well.

I’m making a list of everything to check for when I do it on my next day off. I work a ton and get 1 day off a week. If I can’t figure it out, anybody know a good shop that specializes in brz near LA?

dang, not sure what else to check. the only other thing is make sure the tune has the injectors scaled right and the fuel pump is mechanically functioning is all good. (i doubt the injectors are scaled incorrectly since DT is a pretty reputable tuner.)

The car idles pretty much 100% on the OEM direct injectors so port injector scaling is unlikely to be the issue.
I'd be looking for a vacuum leak or bad electrical connection. |

Interesting, we just had the same kind of problem with a new engine in the Noble. We fouled that a couple of plugs during startup and the computer saw excess o2 so it added more fuel. Making the problem worse. Disconnecting the battery to reset and putting in new plugs and the problem went away.
A lot of what if, head scratching and some language. And finally a good nights sleep before we got it. |
