Read my last post again.. "a wee tad" is not acceptable.. You can't see inside the housing to check the cable itself.. The cable is made up of several strands much like a rope.. If just one of those strands break it will jamb, it's just a matter of time.. What you describe as a "wee tad of stick" could be a broken strand.. Check again carefully..
Will do, full check in the a.m very much appreciate all the insight sir thank you

He’s absolutely right about the resistance factor. The old one on my Jimmy had a lot of resistance when connected to the TBI where, by the time you pushed hard enough to get a reaction from the engine, it’d lurch away. With the cable disconnected, it moved very freely, but something wasn’t right. I just went ahead and replaced it, and my throttle advance has been completely at my discretion ever since and not all choppy.

Vehicle maintenance day #2 was a rousing success! New throttle cable made all the difference, the resistance is ridiculously low on the new one made the old cable feel like it was bent over on itself (i got curious and opened up the sleeve and sure enough one broken strand right plum in the middle). Ran for about an hour between idle and cruising back streets around town before I shut her down and called it good, thanks again sir.

Beg the pard here, I hate to hijack my own thread but whilst I was poking around I saw some bits and bobs that I cant exactly place/look suspect. First off is this return spring supposed to in series like this? I've had to break out this trick before but I knew it was kinda sketch when I did it but seeing as how I dont know much about these trucks yet I figured it never hurts to ask
Also in the drivers side fender well I found this guy just hanging out, looked like some kinda heating element but well like I said I dont know much here.

The return springs look just like mine factory fit. the heating element is a soft plug heater , looks like . Follow it to the other end and see if there is still a 110 volt plug on it. Good job on the repair

One less thing to worry about there then. Any idea on where that heater would have been installed? And why?

It would have been in one of the casting (freeze) plug openings in the side of the block. It's a block heater for cold climates

Oh that's pretty sweet, I really should have known that but it looked different from the block heaters I've installed before. The ones I've done were pretty much nested inside a big brass fitting. Too bad the truck was down most of the winter that could have been handy.

I would inspect and test the accelerator cable and throttle operating linkage for freedom of movement. Its best to release the end of the cable from the throttle lever and then check both for binding or sluggish operation while they are disconnected.

Sorry, no harm intended. Just love Eric Cartman's attitude.
