I drive 1994 Honda Accord EX and I get really bad gas mileage. I get like 20mpg on average.... whats the problem? I checked my air filter and it looks decently clean. Shud I change my spark plugs or fuel injectors?
Is this a recent occurance or over a period of time?
Run the ECU and see if it spits out any codes..
Try switching gas companies..
If that doesn't work, run some fuel injector cleaner...adjust tire pressure, change the PCV valve. Unless you run your tank on empty often, there's no need to look at the fuel filter UNLESS it hasn't been changed in years.
If still bad, it may be driving style and traffic.

Your catilytic converter shouldn't have anything to do with a dramatic drop in gas milage. I have a buddy that drives a 96 civic w/ out a catilytic converter and gets 30 miles. I have a 99' civic ex coupe manual and my catilytic converter had to be replaced cause it went bad, and even when it was bad I was getting great gas milage.
I would say its the weather, I dunno though but my car gets worse milage cause of the weather!
If so, I don't see how using premium fuel in a car designed for 87 octane would increase mileage. The fuel systems in the Accords are mapped for regular grade fuel; it would be a negligible difference in mileage improvement. You're just wasting money.
Rather, run some Lucas or Chevron cleaner through the system as opposed to using high grade fuel. If no differences permit, and your driving style hasn't changed, it's likely just the colder weather. Your decrease in fuel economy comes at the same time the weather starts getting colder.
Remember, there are dozens of variables that affect fuel consumption, from wind to the usage of heat in your car.
I don't know if this helps at all, but my cousin drives a 1994 Honda Accord EX and he gets about 20 mpg (mostly highway, some city). So maybe it's normal? I may be a car enthusiast but when it comes down to the technical stuff, I'm a newbie .

THats what my freind tells me too. But Ive heard some 94 Accords go 30mpg. I mean if I'm paying 20mpg, I might as well get a new car.
I Dont think those are the greatest gas milage figure In my Chevy (5.0 V8 305) i get about 18-20 city and about 23-25 highway, and about 13-14 NYC city miles.
So I guess if your in a city like NYC that might be normal, if not there is something robbing you gas milage. I would check airflow passages, Filter(OEM filter is a little restrictive), Exaust (for leaks) Even sparkplugs.
Maybe your best bet is to take it to some one to see what codes the Cars ECU is giving if any to help pin point the problem.
