So my baby is packing a sad, throwing a tanty. It's a 87 pfl E30 325 converted to manual with 1.3 ECU upgrade.
Currently its missing horribly while accelerating and will miss not so much when cruising along, but will get worse if going up hill.
Another issue ive been having is id be driving along fine and then all of a sudden the car would kind of die. So if revs were 2000 they would drop to 500 all of a sudden then about half a second later would jump back up to 2000 causing car to lurch horribly. And it would do this quite often. I disconnected the battery terminal for a couple hours and the problem went away almost.
