Can't seem to get it to idle clean. With the TPS at idle spec it will not idle on it's own at all...have to feather the throttle. I can get it to hold an idle by screwing in the throttle body butterfly adjuster, but then the TPS is open about 2 percent.

Running a MAF sensor calibrated for 24 pound injectors. It's running way rich at idle, but can't seem to take away enough fuel to lean it down. Regulator currently set at 40psi.

Also found the alternator is not charging...don't know if that is having any effect or not. Looking for some wiring schematics right now to troubleshoot that problem.
