I discovered this afternoon that my '91 YJ came with cruise control... (help)
My '91 YJ has mostly factory OEM parts, which is surprising for a 20-year-old Jeep with only 55,000 miles (I am the third owner and just got it this past May). Well, I was driving on the interstate this afternoon when I shockingly discovered that my gas pedal sticks! There is noticeable resistance after I press down the throttle approximately one third to halfway toward the floor / firewall, and I have to press relatively harder to get past this point of resistance. Once past this point of resistance, however, the gas pedal sticks and does not come back unless I tap / kick the pedal. I've put 1060 miles on the Jeep during these past 3 months and have never before experienced nor noticed this issue.
Someone checked my throttle cable and assessed that it was relatively new and had been replaced recently, so other than that, I really have no idea how to diagnose this, and thus, would appreciate any recommendations on what to check next to remedy this problem...?
Yep. Check the butterfly valve at the throttle body. If you unhook the cable does it move smoothly? The spring will make it kind of hard to move, but it should not stick at any point. And you should be able to easilly move it with one hand. If you still feel it sticking then you know that it's in the TB. I would hit it with some TB or carb cleaner. I would even take the spring off and get a wire brush into every little nook that you can.
Not sure waht to lube the cable with as I've never done that. But I'd clean the heck out of the TB either way.
It's not hard to lube a cable. I like to use the white lith grease that comes in a spray can. I just pull one end out far as it will go. douse it with the spray. Then work it back-n-forth a few times. Then do the other end the same way. The weave in the cable wicks it up inside the cover.
Another good one to use is "3-in-1" brand sewing machine oil. Dunno if they make it anymore tho - check the hardware.
