Message The other day the Z startes to run rough, and I think nothing of it as it was decently cold. Unfortunately, it kept getting worse til it would not even idle. It's been weeks, and it sounds like a wrx, and I get a lot more popping in the exhaust than I did a few months ago when I first replaced my injectors/ECU. I have checked/done the following:

Replaced all spark plugs after pulling one and noticing it covered in black soot.
cleaned the CAS/TPS connectors
cleaned the MAF connector
dealership said the "good" MAF is working properly (even though they thought I needed to connect the "bad one" to the ECU...tried to explain dual intake, but gave up)
checked injector "ticking" and resistance (all right at 16 ohms)

filled tank with new gas. Between the new gas and plugs, it doens't die anymore but still sounds terrible and the power gets a little jerky when it starts boosting. It will still get full boost, but I have been keeping it as near to no boost as possible.

Thinking it could be clogged cats? I have been running a little rich since I got the new injectors and ECU about 7 months ago, maybe they finally got clogged?

running out of ideas. any suggestions?
