So I was having problems with Hedman headers on the car with the steering linkage rubbing on the tube. Also the ground clearance was becoming a issue with parking in gravel. I removed them and put manifolds back on. After running the exhaust pipe and almost slicing my thumb off (please wear gloves) I finished with a set of Flowmaster 40 series. I started it up and it sounded pretty good with a nice thumping. I pulled out of the garage and proceeded to drive down to the main road on post(Fort Lewis) causing numerous car alarms to be set off. Right before the stop sign i gave it just a little more pedal to get it up the incline and it went full wide-open throttle. I proceeded to stop it with full pressure on the brakes and it slowed down to a stop. I shut off the fuel pump and shut her down. I looked at the carb and the throttle cable popped out a little from the recess and was [Edited by Moparts - Family Friendly Site - Keep it clean]-eyed. That caused pressure to be put on the cable so it didn't return. I ignored everything that told me not to continue. I started it back up and idle was good. I made a left at the stop sign and cruised down the road with no issues. I got to the stop light and made a right and gradually gave it a little pedal. Screeeching of the tires told me that wasn't a little. The car proceeded to go 60 in a 40mph zone and i proceeded to go back to infancy. I shut her down quickly and coasted to the next right turn. Same thing again, stuck cable. I corrected it just to get her back home and it happened again without so much drama before I was finally home again. I disconnected the throttle cable and rummaged through some parts and resorted to a old style Chrysler clamp-on bracket for the cable. After some adjusting and double-checking I backed her out again and hoped I wasn't going to have a near-death experience. Nope that wasn't in the plan according to this possessed car. It revved up to 2-3000 and I braked in preparation for it. It then slowed back down to a idle. Any ideas? I've had enough near-death for today and don't want to try it again without being sure.

a pic would go a long ways. whats up with the return spring(s)? if you experience a "run away" throttle situation, just click the key off one click. kills the motor, doesnt lock the wheel. you should also be able to check all this, at home, without even starting the car. stomp the pedal a few times, and go out and look. if it's hanging up, dont drive it, until it's fixed. the liability of knowing there's a problem, and continuing to drive, can cost you everything.

Yeah I'd say the kickdown cable is binding. Can unhook the accel pump rod to keep from squirting alot of raw gas in while you diagnose things in your driveway

hard to tell from the pic, but it looks like the bar to the kickdown is binding slightly. where you have the rod bolted against the adapter, i used the stud from the original linkage, with the hairpin clip to mount the kickdown. i'll have to see if i can find a pic, as the ride is gone, but the smooth stud, threaded on one end (that i mounted in the adapter) and then i put a flat washer on either side of the rod where it mounted to the stud, held on with the clip, and i used a paired spring set (smaller one inside of the larger one, not side by side) and everything was/is free to move without binding. i'll see if i can dig up the pics. edit: here's a pic of the stud i mentioned. ignore the writing, was the only pic i could find quickly. i found the pic on this page, which has very detailed instructions on how to properly set up the edelbrock stuff, in your ride. http://www.bouchillonperformance.com/bpetkdcinstructionsnew.asp

I do have that stud. Don't really like cutting stuff that is hard to find(not in your average store) but if that fixes the problem then that's what I have to do.
don't understand why you would have to cut anything. if you have the stud then install it where you have the bolt. you could also try a long bolt,two nuts and a few washers as long as the slide link slides freely back and forth with no bind.

The factory throttle cable is available from different sources... An E-body uses the same cable. http://cgi.ebay.com/ebaymotors/NEW-71-74...=item3a6645764dFrom what I see the kick-down plate(slotted) is touching the wrong end of the carb stud. It should be on the back-end that way when you give it gas it starts to put pressure on the tranny throttle valve right away. so even with the correct stud the tranny kick-down won't work right. need to adjust rod out or replace it with a longer one. I probably have it but seeing you need it now...
