code 12
Hello All:
I'm a semi-proud owner of a 95 RRC. I'll be 100% proud once I get the code 12 problem resolved. Ever since I bougth the truck, I've had a CEL with a Code 12 and the truck ran terrible. So I swapped the MAF, and the code 12 went away. To make long story short, I then got codes for the TPS, and Engine coolant temp. sensor, so I replaced those with new parts. Then Code 12 came back. So firgured maybe the cats/exhaust/o2 sensor needed to be replaced. The cats/exhaust were shot anyways, no big deal....wth all that done I still have code 12. Any ideas?
the truck has no problems starting, but still run roughs with misfires
leaky injectors? maybe I installed another bad MAF? fuel pump?
