well I had DTC 19 because my dumb *** forgot to plug in the connector after replacing the IP. Reset the codes and it went away. If some one know about the throttle reset thing that would be greatly appreciated as to how it's done. One more thing..... can I take a 1997 ECU and use it in the 1994? Wait Strike that 97 is OBD II
1994 C2500 6.5 TD. No mods, completely stock.
