My truck has done this a few time before, but it has really gotten annoying. In the morning after a good frost or a very cold morning, it seems that my gas pedal sticks. I go to pump the gas before starting it and the pedal doesn't come back up. I run the stock gas pedal setup with original pedal/cable and its connected to a Holley 600cfm carb. I can somewhat loosen the stickyness by spraying into the cable with penetrating oil and working the throttle linkage by hand. The gas pedal will return but it takes a second for it to come back up and will tend to stick just above idle. By the time the engine is at running temp the gas works perfectly with an insant return, like the way its supposed to work on anyother day. I already have 2 throttle return springs on it, do I have to add another? Also maybe I just need a new throttle cable?
