+1 but id do it with the car on jackstands in the rear and with the car in gear like u were driving it

 

I removed the old return spring and installed a new one last night. The car seems to be doing ok but im still apprehensive, she is very crafty. I will put some more miles on her tonight and see if she is still in control.

 

Motor mounts look fine i see little to no wear on them.

 

I had the exact same problem years ago. It was the motor mount. I can't recall if I could visually see the failure, but your symptoms are vey familiar.

 

return spring,,is number 1 !!!!!...exhaust flange to arm......after that look at ( AND I KNow ) it's crazy but nylon washer for the choke/clear issue.........Just got by the same friggen issue,,it's deff a link issue

 

Just wanted to say thanks to those who replied, your comments helped greatly. I had installed a new return spring a little under a week ago, and the demon is no longer. I have complete control over acceleration. I bought a return spring from a local auto shop and its rigged up pretty shotty. I am missing the return spring bracket so for the time being I had to coil one end of the return spring around a bolt that the previos owner was using as some sort of custom bracket. So far it runs fine but fixing this is on the top of my to do list. Any recommendationg on an accelerator bracket or would anyone be fine?

 

glad to hear you got it fixed having a throttle sticking isnt safe

 

A cheap little throttle return spring beats having to swap out a motor mount any day. They sell aftermarket brackets at just about any good auto parts store. I'd make it the number one fix on the list... cheap, easy and dangerous if you don't!
