ecm

[ony]

what ecm is suppose to be in a 1995 chevy k 2500 4 wheel drive 5.7 automatic? I have one at work an my little sacner showed the prom id as 346 its never showed a # that low. truck runs bad at idle, my autoxray picks up pending codes an it had 3, low tps it is at 68%, iac malfunction, o2 not right. I am going to pull the ecm in the morning to check the #s. just wondering what was orginal equipment,someone has spliced a different map an tps to it, my luck [someones mess up that I have to mess with]
