    Love my old Burby but these quirks needs to be fixed. The hood cable is not consistently popping the hood. Sometimes we have to tap on the hood quite hard to get it to pop or even drive around & hit a bump to get it to pop. I'm assuming the cable is stretched. What do we need to change to fix the problem? I've tried extending the bumpers out under the hood & that worked for awhile. Time to get it fixed.

    Problem #2

    The throttle is getting exceedingly sticky/stiff. When you push on the gas pedal it sticks.

    Is changing the throttle cable hard or what can we do to fix the problem. We are pretty handy (husband & I) but need some pointing in the right direction.

    Thank you.

    I had a Chevy Astro that the hood wouldn't pop. Took 2 people to get it open, 1 to hold the handle and 1 to hit the hood. The new owner said he sprayed WD40 on the catch mechanism and it now works fine.

    Replacing the throttle cable is pretty easy. Replace it before it breaks and leaves you stranded (I know this from experience).

    I took lithium grease that comes out of a spray can and i sprayed on the mechanism.

    Your talking the hood?

    I'll try this.

    Are there directions anywhere to replace the throttle cable? Thanks!

    before replacing the throttle cable check for lubrication points, as it may just need to be lubed,

    I have 1990 Suburban that had a stiff throttle. The previous owner had it in the wrong location. I removed it, lubed it with silicone & me & my wife moved to different locations as she pushed peddle. Took about 10 minutes but made a big difference. Will purchase new cable soon though.
    The hood needs to be cleaned & lubed(ALL) and might need to adjust hood latch that may be binding. Do soon before cable breaks!

    I had the same two issues on my 88, the hood popped open after I shut the door haha I kinda liked that, but I sprayed both with wd40 and it works much better now

    ahhhh wd40... a wonderful thing. It did the trick on the hood latch. Now on to the throttle.

    Thank you.
