Any lifelong Mopar Techs that remember the OBD1? ...Fuel Sync Question..
Swapped a 5.2 from another truck that was getting 15mpg. Did the timing chain and Dist because one of the tabs broke while disassembling. I marked everything exactly & it runs well EXCEPT MILEAGE!! I discovered this Fuel Sync procedure using a meter. I see there is a procedure using a good scan tool, but not sure if there is something for OBD1....
So for you guys that have done this is there an option for an OBD1 truck and is the meter procedure as accurate as the scan tool... Or any other suggestions?
