[dpzelenak]

best bet is to pull the codes thats the only way to know whats going go

 

[gunsn88]

thats what im going to do as soon as i can. i have a vacume leak around my tb to. because i took it off and didnt clean around the seals i think when reinstalling it.

 

[dpzelenak]

the leak might cause a code depending on how big the leak is
take it to any auto parts store and have them scan it for you and write the codes down and post them on here so we can help you get it taken care of

might need a case relearn. aint it a 50 50 shot when you change the pcm?

 

[gunsn88]

ok will do. thanks alot. ill have to do it this weekend though. ill get back to this thread as soon as i find out the codes.
