305 TPI right bank running rich and HOT
hey guy, iv posted afew different threads trying to narrow down my problems, getting close but now my 87 305 TPI is running very rich and hot on the right bank only, and just runs poorly. any idea why just one bank of cylinders would? the left bank is running great ( nice golden brown plugs) but right banks are black and sooty. anyone else ever run into this nightmare?

The two banks are wired separately all the way into the ecm, so its probably a wiring or ecm issue. You can tie the two together at the ecm (tie the bad side into the one thats ok and leave the pin out from the bad side) and see if that cures your ills.
