I finally got my new GM replacement motor in my 94 C1500 350 TBI, but it is idling really rich, my wideband 02 was saying 10 to 1.( I borrowed it from another project car.) I replaced the Map and two pin coolant sensor/switch, and it still was idling rich and seems to have overdrive locked out. I have the cable and box to read the information going to the computer and it is saying that the coolant is about 190F and it still runs rich. Did I forget to hook something up? Is there a way to tune around it? I have a Ramjet roller cam in there as well with the stock TBI head.
