Angelo Voltura Posted March 12, 2022 Share Posted March 12, 2022 Here's a new one for me. 302 EFI, AOD. Drives fine, runs good. No shifting issues. Gas pedal is like a ROCK and takes CONSIDERABLE effort to press. I replaced replaced cable with a new ATP cable, cleaned the throttle plates, lubed the springs and the TV cable, even replaced the gas pedal with one from a 6 cyl truck. With the cables disconnected I don't feel any binding in the throttle body from worn bushings. I'm starting to think it's either the TV cable or the valve at the transmission. It actually starts to make my leg hurt after just a few minutes of driving. The truck only has 106k on it. It is an absolute chore trying to drive and I have never ever felt any other EFI engine with a pedal this stiff. What else can I check? It does have smooth action and does not feel as though its binding anywhere. Its just STIFF. It's bad enough that I honestly don't even want to drive it.

Gary Lewis Posted March 12, 2022 Share Posted March 12, 2022 How about disconnecting the TV cable and operating the throttle? Link to comment Share on other sites More sharing options...
mat in tn Posted March 12, 2022 Share Posted March 12, 2022 I'm guessing this truck is new to you by the way you describe this issue. you did not say "it started to do this" certainly, you could reach over and work the throttle with it not running and feel the effort it takes. then disconnect the trans end and test again but does the truck have cruise control? I would start by removing the piggyback connection to it at the throttle cable. in order for the drag to be inside the trans that would mean the tv is binding. not very likely. it is internally spring loaded in the direction you are trying to move it. the cable has an opposing spring to keep the internal one in check. these two keep the cable, lever, and valve very in sync with the valve body which is full of fluid hopefully. more apt to leak then bind. I'm sure it's possible for the tv cable itself to be a drag whether from rust /corrosion inside the sleeve but I have not seen the condition myself yet. maybe in the rust belt it has been more common.

Definitely hand-operate the throttle lever from under the hood, as the others suggested. My gas pedal had a similar issue and it wasn't until I did this that I noticed the PCV tube from my driver's side valve cover was run just where the lever needs to move. If the air cleaner housing was tightened down just so, the tube would press on the back of the lever preventing it from moving properly. Not saying this is your exact case but maybe you'll see what's blocking it "from up front"... Link to comment Share on other sites More sharing options...

I'll have to disconnect the TV cable. Operating it by hand I feel nothing binding and nothing is hitting it. With the TV attached it feels smooth. Just stiff. No change by removing the cruise control cable. It just feels overly stiff. I've never felt one this tight in any of the injected trucks...it feels like it's got 3 of the stiffest carb throttle springs you can buy. Link to comment Share on other sites More sharing options...

I've never felt one this tight in any of the injected trucks...it feels like it's got 3 of the stiffest carb throttle springs you can buy. then i would recommend disconnecting both ends of the tv cable. the lower end is on a ball stud. the upper on the t post. then operate the cable from the upper end checking for smoothness and resistance. the lower end has a corrugated rubber cover covering a load spring to hold the internal tv spring in check. the internal spring will put tv pressure way high and not modulated while driving if it is disconnected at the lower end. it will be low and not modulated if disconnected at the upper end. DO NOT DRIVE IT THAT WAY! if you do than we will be glad to have your business here at transmission masters . Link to comment Share on other sites More sharing options...

I've also been told to take the e clip off the throttle shaft and clean that so we will try that and report back after the new oil pan, u joints and lift kit go in this week.
