Gear shifter locks in Park, with car on; RPMs fluctuate wildly
Last car drive was city traffic, stop & go. Rpms wild, all over the spectrum, and putting it in park to try and tap the accelerator, it locks in Park. Ended up turning it off, using key to unlock the gear shift, and roll the car to the curb. I've thought of using two keys- one to unlock gearshift, one to stay in the ignition to keep the steering unlocked-and try restarting it. Afraid to try it. Anyone have a similar experience? Any thoughts on what the problem(s) could be?
