So I have this weird problem. From one day to the next, without anything touched or changed, my car likes to go WOT when I pull out of a standstill. This is quite scary if you're gently attempting to drive out of a parking stall or at a crosswalk, not to mention the looks of dismay as the 383 is getting to work full blast with squealing tires. It seems to stay in WOT until 2nd gear, where it drops back down by itself to whatever the accelerator pedal is at. I checked all the linkages, pedal and springs. Nothing seems stuck, loose, broken, binding, sticking or what have you. I disconnected the kickdown linkage to see if maybe something was affecting the throttle linkage, but it made no difference.
This only happens if I come from a standstill. As soon as I go 10-20mph, I can't replicate it.
It's not doing it in reverse either.
For years it was fine, until from one day to the next, it decided to act up this way
Chrysler '66 300. Engine is a 383, pretty much stock, aside from edelbrock 383 intake and Edelbrock 1406 carburetor, with the factory transmission.
Maybe someone has a few pointers for me to look at?
All help is greatly appreciated
