PCM Help
man run a check on your codes...and if your not really advanced with the lt1 then have someone higher than you look at it if you dont think its something taht you want to tackle
or you could just convince him to buy that way he has it when he is forced to do these mods haha..jpbut hey seriously man run the codes first and tell us what you get...if you want to tackle this yourself seriously call speartech on this..they will def help you out..they are amazing with wiring on these cars and computers...they will tell you where this could be coming from pretty much on an exact note...goodluck and let us know what you find out man

I got code 4 codes pulled today..
23: IAT temp too low
26 : EVAP Solenoid Control circuit fault
37: Brake switch stuck on (ABS light)
51:
EPROM/PROM Error
IAT is easy, it got wet so thats prolly why its messed up, the EVAP I dont kow about that one, and the brake switch on? Probably my brake pedal is hitting the brake light switch, and the EPROM error... I hope I dont have to buy a new PCM

Verdad Gallardo 51 buddy....sounds like a good one to take a look at..but get those others taken care of...lol..26 might be another one to take a look at and then see what it does when you take care of those...you really need to take it to a shop though on this if you dont think you can tackle it bud
I can tackle it. I know my way thru wiring and can follow instructions and know how to work a multimeter quite well so it wont be hard. Im gonna take the dumb gound a shop added into the pcm off the tan/white wire and use a new one and go from there. That code be a fluke from bad grounds....
[edit] If it matters. but if I idle for a long time my volts will slowly start to fall.

wow that sounds like a ground....what do they read before dropping?? seriously though call speartech they are the best 765-378-4908...tell him is going on and what kind of things have been done to your harness and he will tell you what he can go for you.. where are you from? cuz if you can take your car to him in anderson indiana or send your harness to him he will go through it and fix whatever needs be fixed for not much at all...hes really good on his prices bro
check your alt grounds and go through and look for cuts and loose cables on all your grounds...a battery cannot not destroy your pcm nor could it fry it if your battery went dead..its a ground or something isnt right with your wiring...good luck with this again
