One thing I've yet to see and seems like common sense but change your oil every 3000 miles with 10W30 (for older original engines). Doing so also increases your mileage.

No one has even mentioned O2 sensor yet. They can start to go bad and give false readings, but not throw a code/CEL. If a regular tune up doesn't help, that is the next thing I would replace.

Thought id chime in. My old 90 lx automatic used to get 400 to the tank then ione day it sunk to 300-320. Never looked into too much as 320 matches up with the mpg estimate. Now that i saw this though it may be something serious. Id like to know how tmhe tune up goes.

My ex doesnt even get 300 per tank

I read on this site that the fuel tank capacity for my 90 EX is 17 gallons? but when my low fuel light came on, and I topped it off it only took 13.8? so does that mean my tank is smaller? or there was 3 gallons still inside it? I am just confused as to why the low fuel light came on?

And I am lucky if I am getting over 200 miles per tank, granted it is all city driving, and the guy I bought it from told me it has new plugs and wires, but the wires dont sit tight on the valve cover? and my honda buddy told me if he bought cheap wires they are not the right length? they are too long is what he said, but I am a chevy guy, none of this makes sense to me lol

i have the same problem my 92 ex cant even break 300 per tank ? have done normal tune plugs wires cap rotor fuel filter. i just bought a bottle of sea foam and gonna try that i have heard that msd might help from other just small talk tho im just wonder if msd would help mpg or is that just a performance mod ?

I'm losing gas about 100 miles per tank its pretty ridiculous

I was asking my mechanic he said my spark plugs were really bad,

is there a certain brand i should buy for spark plugs or generic would be fine?

I don't mind spending extra money seeing its for my car's daily performance

How much should i spend for the service?

I like this thread, lots of informative topics in it, but permit me to share mine. I have the same problem like yours, I started replacing parts as per my mechanic advise (Fuel filter, TPS, IACV, FITV, Fuel pump, Fuel injector and Clean EGR passage) result was still the same until one day I find out that my distributor was leaking with oil then I decided to replace it with OEM good second hand from the junkyard now my problem is gone. Hope my experience give you some good example.
