running rich
#2
Many things can make an engine run rich. Have you scanned the ECM for codes? However, the usual culprits are: misfire, bad pressure regulator, stuck open injector, bad ECT, bad IAT, bad MAP, clogged air filter, bad MAF if equipped, restricted exhaust. Have fun.

Make sure the control leads to the injectors are not shorted to ground, as that will hold the injector open at all times. Your engine still uses batch fire, so that an entire bank is fired at one time, a common control lead is used to fire each bank.
