Q My '03 Mazda MPV with 125,000 miles has the Check Engine light going on and off the past few weeks. The parts store's scan tool found a code for catalytic converter issues. The manager suggested I try a couple cans of Sea Foam or a product called Cataclean, which I've never heard of. It's about $25 for a 16-ounce can. Do either of those products do anything to revive a tired catalytic converter? Hate to spend foolish money on a long shot. The vehicle runs perfectly and has no unusual sounds or smells.

The build quality, alloys and galvanized steel used in modern automobiles has reduced the need for additional rustproofing.

It is quite possible that the symptoms of delayed engagement and slippage are the result of using incorrect transmission fluid.

It comes on every time the car is started.

The only way an oil pump could "fail without warning" would be if the drive shaft or impeller suddenly broke or if the oil pump pickup tube fell out and dropped into the oil pan.

Typically, the flashing "check engine/service engine soon" light points toward multiple misfires and a significant amount of excess unburned fuel reaching the catalytic converter.

If it's not the windshield, the most common source of water collecting on the front floors is a plugged drain for the HVAC evaporator housing.

This is an irritation, if not a hazard, but an experiment shouldn't also need $250 to $300 in parts plus labor.

A I'm glad you included the fact that the passenger door "always turns things off." That's a key piece of information. The VSM (vehicle security module) located in the passenger footwell individually controls the driver and passenger door lock/unlock relay. This module or its connections may be at fault.
