Would some carb cleaner help? Maybe a new fuel filter? I'm looking for some suggestions.
Car has 138k miles.
Thanks in advance :-)

Pour a can of fuel sysyem cleaner into the as tank too. Might as well try all the easy/cheap fixes first. Get the kind that cleans the carb/fuel injectors, valves and combustion chamber. I use this stuff once a year. Often there's a very noticable difference, depending on how clogged up the system is.
A plugged cat could be the problem. You could cut off the pipe directly behind the cat, and then ream the cat out a bit with a hole saw, to improve flow through it. Then start the car with the cut pipe still not connected, to blow out the particles in the cat. Only do this if you don't have to worry about passing emissions, of course. Otherwise get a new high-flow cat put on. On my 86 MR2 I recently put on a new cat, The old one you could barely see thru, even holding it up to the sun! Gas mileage and power went up considerably, and oh yeah it passed emissions.
At the risk of insulting, I presume the air filter is fairly new? I once bought a car with 42K miles that had the original air filter still on it. Horrible gas mileage. When I discovered the old air filter, first I cleaned it and got better mileage. Then I replaced it and got much better mileage.

If you have your fuel pump in the engine compartment, it & its filter will be near the firewall right in front of the driver. I think this applies to early 80s subes, like 80 and 81. (Experts please provide more detail.)

PS. It's been backfiring a lot latley. Could that have destroyed my cat? And how would I fix the backfiring problem?
