[DML] Re: Maybe Catalytic?

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

You didn't mention how long it has been since you did any type of
tune-up work on the car. Fresh gas is always a good thing to have.
Using a good injector cleaner once in a while is also a good idea. I
don't think you will change the #'s much using different octane. IMHO
I suggest a tune-up changing the fuel filter, spark plugs, ignition
wires, distributer cap and rotor, all the little vacuum lines, and
cleaning and testing the injectors. I also would check the ignition
timing and the mechanical and vacuum advance. If all this doesn't
improve your #'s you  *may*  need a catalytic converter.
