I just took a quick break at work to see if it was the vacuum line to the transmission that may have popped out. The hose seemed fine and in place.
I then started the truck and revved it. It hesitated - bogged?
- and didn't want go beyond 2000 rpm.
I then reversed the truck a few feet and then drove forward again to see how it did. It exhibited the same hesitation as earlier.
Could it be a stuck/sticky choke plate?
I'm at work for another few hours and might be able to step out for a few minutes to tinker with it. If this seems like a quick fix and you guys can give me any hints, it would be greatly appreciated. Thanks!
