While driving the engine seems to cut out or stall, the RPMs drop to 1500. If you let off the gas it will correct and run normally for a while. It does this whether or not you are accelerating. We have not had the O2 sensors replaced yet.

Welcome to the forum, how long since a tune-up? Use a gage and check fuel pressure. You may need to clean the throttle-body and check any sensors on the throttle-body. Have the trouble-codes checked, some of the national brand autostores used to check codes for free. You can call and ask.
