5.3 swap in my s10 using the factory 5 speed. 3 things seem to not be working correctly. I may have to try and swap the pcm out if I can't resolve this
Pcm is originally out of a v6 4.3 s-series truck. I have changed everything on the tune for the 5.3.
I have the ses light flashing at me only code is p0300.
Fans are running constantly which don't know why. As soon as the truck is started the fans run. Which i have fan table enabled and correct temps in.
Speedometer works. But if I floor it the speedo cuts out from wherever it reads and after slowing down to around 30 it comes back. It will repeat itself many times like that. I've babyed it around the block with flooring it and it stayed working for over 7 miles.
Any help is greatly appreciated.
