Hey guys, I have an 87 silverado with a 350 tbi eng. and 700R trans. My gas pedal is hard to push. I've tried two different tbi units and the last one I rebuilt. I have a brand new throttle cable and the trans cable is adjusted correctly. Am I missing something? I've had other TBI trucks and the gas pedal was normal. I am doiing jackrabbit starts every time I take off. Anyone else have this problem?
-
Nope. Is the cable binding?
-
Nope, new cable
-
It could still be binding. Did you lube the sleve around the cable that comes out of the firewall?
-
Disconnect the cables and turn it by hand. Hook up one cable at a time and see which one is giving resistance.
-
Check the pedal in the truck....
Unhook cable and see if the pedal is binding...
-
Do you have a return spring hooked to it?
-
Thanks for the help. Soon as I figure this out I'll post the fix.
-
How stiff is your throttle return spring? That could be a culprit as well.
-
If you have a spring on a TBI THAT is the problem. The return spring is built into the Throttle body.

i didnt know that capt. Pretty interesting. I figured that when you asked if it had one that it was supposed to.
