New to the group. Have a 96 , replacedEGR valve, map, crank, cold air intake sensor, temperature sensor, distributor, cap rotor,plugs wires,O2 sensors intake and updated injectors.
Truck was running rich, after all installed still running rich smells like bad gas.. Also when warmed up at higher speeds bucks when holding gas steady, the bucking issue was after all was installed. Found out unplugging the EGR stops the bucking.
Still smells rich.
Any help??
Thanks

things seem to be labelled wrong on the scan tool so its hard to make sense of some of it.

fuel trim bank 2 is rich so what could effect only 1 bank....bad 02, so i look at the 02 reading for b2s1 and can't find it.

what type of injection is used...tbody, spider?
