    I have a 1990 gmc jimmy and have had a problem with the gas. when i hit the gas it catches someplace and causes hte gas to get pinned down. its not bad, i can still drive the truck but need to pass inspection and they wont let me with the problem. The truck also shackes really bad but only when ii have my foot on the gas, if i take it off then it goes away untill i hit the gas again. if you know how to fix any of these problems please elp me out. thanks

    For the gas problem, your return spring is most likely getting hung up. I replaced mine with a higher tension spring and haven't had that problem since.

    For the vibration under throttle, replace your U-Joints, and I'll bet it goes away .... well, 90% sure it will go away.....

    I have solved the gas problem and now i am replacing the oil pan gasket becasue that $hit the bed. but i have also have a heavy vibration comeing from the truck, i have a feeling that i might have lost some of my wheel weights and thats whats causing the truck to vibrake but if you have any other ideas let me know. Thanks

    Is the vibration constant, or only under throttle? Does it get worse with increased speed? What happens if you shift into neutral at around 65mph; does the vibration go away?

    If it's constant, then the weel balance may be it; but if only under throttle, I would still go after the U-Joints first. They are the cheapest/easist thing to replace first.

    BTW: What solved the gas problem?

    Thomas.

    I used some wd-40 to fix the throttle, i guess the grease caused it to stick and i havent had a problem yet. i found a wheel that is missing the weights so as soon as i get the oil pan back on i'll put on the spair tire and see what happens.
