well if you arent sure what code 51 refers to..
"Code 51: Defective PROM; PROM not properly installed; incorrect PROM installed; Defective ECM"
so now i'm not sure what to do, i guess i have to swap out the ecm and prom and now spend big bucks to get one custom done AGAIN. i wish i knew how to burn memcals right about now... plus i gotta find a good 730 ecm, not hard but who can i trust....ugh. i'm not happy at all, i was going to try to set timing tonight on the monte and now this.... piece of ****. Â*im just surprised it did/does run how it does with that ecm/prom issue...oh well, its just my luck. Â*Can anyone help me? please....i got parts to trade Â*
