Got exhaust ran today! And driving it to the shop I had a few problems (including blowing the water pump).

Hopefully I can get a few answers for my problems:

First, when the truck has been driven for a while and is up to temperature, i come to a stop sign and it will want to keep going and if i press the brake to try to stop it it will act like its going to stall out. So I have to put it in neutral. But when its cold i can stop and it will idle just fine with me on the brake.

Second, I cant get my speedo to work. I have tried hooking nelsons green speedo wire to my Light Blue w/ white stripe wire and nothing happens.

Third, my RPMS are way off. The tach is reading 1,000 when I am going 55 (using gps). Keep in mind I have 4.56 gears lol so I know that isn't right.

4th, when trying to confirm the RPMS with a scan tool hooked up to nelsonss obdII port, it says it can not communicate with the ecm. And the check engine light thats on their obd connector is lit up so I know it has power.


Other than those issues and the water pump, the truck drives like a dream. seems so smooth and takes absolutley no effort for it to take off. pulls really good on the top end for sure. its way stronger than my last cammed out crate motor. Ill get pics of the exhaust job, it looks really good i'd say we did a pretty good job going from the headers to a y merge pipe to a electric cut out to a single in flowmaster to dual out.
