The car acts up when it warms up.come to a complete stop it surges the rmps and oil presure goes up and she tries to drive off, as if i were double pedeling. so much i have to put both feet on the brake then her rpm bob spasticley.the rpms don't exceed 1 and there are no codes coming up.i did have the ho2 sensors replaced,but i don't think thats it . they've been checked since then.it's a graduale problem it keeps getting worse. i'd like to catch it before i end up needing a tow.

You could have a very bad throttle positioning sensor. Usually, they go bad and have erratic values at either zero or full throttle. Let the car warm up and then pop the hood and unplug the sensor while it's still running. If the RPMs level back off to close to normal while it's unplugged, it's more than likely the problem.
