944 rough runnin'!
1986 944 NA runs rough. We replaced the fuel system back to front, checked the injectors, tps, new 02 sensor, cat was not blocked, afm retracked, new gaskets on the intake, new reference senders, no vacuum leaks, and it just runs like ****. Rough at idle and won't make power over 4000.
Any ideas out there? About the only thing I haven't done is rebuild the throttle body, but I can't seem to find the rebuild kits that used to be out there. Arnworx is gone? Don

I don't see anything about ignition/plugs/cap/rotor done. What have you looked at there?

What do the plugs look like after it's rough-idled for a few minutes?

Whats your fuel pressure?
Did you replace the DME temp sensor (blue top)?
