I bought a 2005 Lly duramax a few months ago. When I bought it there was a bad transmission in it. I swapped it out and everything seemed fine. Shortly after I swapped out the water pump and now that its back together I have little to no throttle response. I can floor it and the rpms will go up...
Current known Issues
1)Black smoke coming out of Tail pipe
2) Using Edge CTS3 im not getting a reading for one of my injector rates (bottom right on the cluster)
3) Terrible throttle response
4) bad gas Milage
5) randomly getting a low oil pressure warning
Im going to go ahead and guess...
