my car has got to be running rich as hell no i dont have a air/fuel gauge so i cant tell but its killing gas and my idle problem isnt helping either it idles back and forth from 1 to 2,000 rpms wont stay static i guess its the TP sensor but what can i do about it running rich..

one of my friends was riding behind me the other night while i was racing someone else and he said when i hit the gas a flame shot out of my exhaust

Bad O2 sensor? Is it throwing codes?

Fix it quick, unless you have an extra catalytic converter laying around.

Are you throwing any codes? When my car ran rich, I replaced the O2 sensor, did the usual tune-up and advanced my timing. No black smoke at all now, even at WOT in VTEC.

Well im running rich also and im getting like 275 miles to the tank and i have a air fuel gauge is its as far on RICH as it can go. im getting a tune-up today and the guy called and said he do my fuel filter and clean out my fuel system for 300 bucks, do they think i am that stupid b/c i am a kid?? but ill tell you how the spark plug tune-up goes.

thats the thing i have a testpipe no cat so i guess its normal every once in a while to do that but it still eats gas badly i guess i should take it in to a honda specialist get everything straight.

Just how bad is your gas mileage? I doubt a Honda "specialist" will do **** for you. If it comes down to it, get a VAFC and a couple hours of tuning on there. You'll net more power and have a better running engine. Now could that "specialist" do that for you? Sorry, I just hate dealerships

Fast&furiuslude, 275 to a tank sounds OK. That's what I get when I get on average. But then I drive constantly at 4k+ rpm.
