Question type: Maintenance & Repair

She has 268,000 miles but has had the head gaskets replaced again 8,000
miles ago and valves done 68,000 miles ago. replaced fuel filter last fall. I am
just lately getting real bad gas mileage, about 12mpg, and it balks when
trying to keep an even speed like riding a bull sometimes at lowest speeds
in traffic. Are these symptoms of a Fuel Pressure Regulator? or something
else. I was told by a mechanic at the dealer that the regulator was likely the
problem.

I would also check the catalytic converter.

Get new irridium spark plugs for mpg. Doesn't cost too much either.

Also z-max fuel additive helped mine. I'm at around 13.8 city and don't drive slow at all.
