Throttle pressure / Spring Load / Stiff accelerator

[stolen86]

86 5L
Was originally a manual transmission, was swapped to AOD by previous owner. I just set it back to manual.

The accelerator pedal is very stiff...is there a way to modify this or is there a different spring available?

Thanks for your help.

Is it the throttle body? Pop the throttle cable off and manual move the tb blade. It could be seizing up or rusting closed?

Also, the cable could be going bad as well.

The stock spring is not that stiff, so if yours feels stiff it's more than likely a problem somewhere

Found the issue...I accidentally left the kick down cable attached to the throttle body and it was binding up the lever.
Thanks
