I had the instrument cluster loose today at work to lube the speedometer cable, halfway through it I had to pick up my daughter from preschool. I ran it with the instrument cluster loose which kept the alternator from charging, i shut it off at home and had to jump it to get back to work. At work I figured out the whole alternator charge light thing, the battery is old and didnt pass a load test after charging so I replaced it. After battery replacement the car will randomly die. Set a code 42 est circuit failure once and then it did a code 51 eprom error thereafter. Which puts it in calpak mode which doesnt agree with my 60 lb injectors and translator plus/extender setup too well LOL. Unhooked the ecm and reset it and it sat in the driveway and ran fine for a long time. I didn't know if it was just a random glitch with battery replacement or if low voltage driving around town might have damaged the ecm or eprom. I have a spare ecm with turbotweak chip I can throw in it if it does it again, and I'll know this weekend when I take it 2 1/2 hours from home
. Has anyone ran into a similar problem? I can't drive it anymore over the next couple days, gonna road test it on the way to KC.
