Your idea on these problems
 

So recently I have had the following issues come up:
My engine revs in cycles (800, 1000, 800, 1000 rpms) on start up periodically, but a press of the gas and the cycling stops. Idles fine.
Humtech mentioned that the TB might need cleaning, but having gotten a chance to do that yet

The new issue is that when I start the rig, the normal quick turn and release and the truck starts doesnt happen. I release but it seems as if the starter cycles for a second or two more before actually starting the truck.

Could the two be related? I dont know. So I am asking our group what they think
Thanks in advance
