Had a bad mount in a 69 impala back in the day and had similar issues as you until it finally broke...then while giving it gas going around a corner in would damn near give it full throttle= not good!
Yikes! I think the motor mounts are solid but now that makes me want to check again!

Re: Accelerator pedal resistance - 70 SS

After you have done all of the items above, try loosening the 4 bolts attaching the carb to the manifold. After they are loosened, retighten lightly. Often an overtightened set of bolts will warp the base and make the throttle shaft, or butterflies bind.

Re: Accelerator pedal resistance - 70 SS

I had a Camaro that had a bad motor mount. The accelerator cable would work great at all times except WOT. When you went WOT, the engine rose up and the accelerator cable would get stuck. The only way to slow down or stop the car was to turn off the ignition. It was a scary situation and it took a while for my brother and I to figure it out.

It's been well over a month. Have you figured out what was causing the resistance?

Re: Accelerator pedal resistance - 70 SS

FWIW look closely at the firewall area where the pedal mounts to the floor. Could be in the kickdown switch or a broken plastic pedal mount.

Unfortunately, no. The car was held up in the paint shop until just a couple of weeks ago. Finally finished the job that was supposed to be done in June. Then he wanted it out ASAP. Then I had to drive it straight to winter storage. This is her right after I parked it. It'll have to wait until spring because the place I store it doesn't want me doing repairs and stuff while it's in their garage.

Nice looking car. Too bad about the storage facility rules. Winter time is when I do most of my repairs and upgrading. Working on my car is the therapy I need to get me through the winter.

If I could "love" that comment, I would. Same here. I won't be able to work on my 70 but I have a 69 SS that needs some "therapy". I'll be restoring the core support and putting in a "new" Muncie. The car and I will both benefit from winter therapy
