btw what engine do you have?

i had the dealership "reset/reprogram" my ecm (as i went to look for one on rock auto and auto zone i seen they are referred to as the ecm not pcm) and it still didnt change anything. an engine right now happens to be my main priority (M^@$(&R F@&+!#R)

*stomps feet, pouts, punches things, cries, dazes not wanting to be in reality anymore* so after i get that ill see what i can do again about the puter. who knows...maybe ill find that bad ground while we have the engine work being done???? time will tell.

my bad...the engine is a 3.4. cant just call it a 4cyl or 6 cyl...the numbers confuse me in chevy engines.
