my 98 240 has 116,000 miles on it
i know i know its alot for a 98
thing is i only get bout 200-250miles for a whole tank
i know this is really bad and i was wondering what could help?

spark plugs, wires, fuel filter, some solution to pour in ur gas tank?

i cant really think of anything else
any help guys?

thanks in advance

 

search tune-up
biggest thing is 02 sensor, when was the last time you did that?
fuel injector cleaner, plugs, wires, cap, rotor, gas treatment,
how long since you did a tune-up?

Dr.

 

this is one of my concerns now as well I just put a full tank in it only got around 20 miles since I filled it up and I'm already on 3/4 so if that continues I'll only get about 80 miles this tank I put some gumout in it I'll let you know how it goes

 

Do a FULL tune up. Run a little fuel tank cleaner. clean your injectors?

 

okay i'll see what works n hit u guys back
thanks again

 

All righty, good luck on it

 

BTW what kind of spark plugs do u guys recomend?

 

NGK, iridiums
worth the $

Dr.

 

o yea n that dam engine light is startin to get annoyin
i noe its probably the gas cap
but i dont think replacing it 3 times will really help
could be something else for all i noe
any idea wut it could be or should i jus leave it alone

dammit the more i think about it
the more problems my car really has...

 

i wouldnt mind buying the car, lol.

If you can, check the codes that the ECU is throwing out to see what the problem is.

 

well well, replacing the gas cap three times, maybe that's why you losing gas. evaporation.

 

yeah, but thats a lot of evaporation. Check the whole seal around the cap and everything, I doubt you got 3 defective gas caps.
run ECU diagnostics as well, email me if you want them, I just posted them like 2 days ago on here as well if you wanna search.

Dr.

 

i didnt replace it three time i've read people have so im not gonan bother
i never replaced it once
and i found the codes on ka24development.com

 

awesome dude, hopefully thats a step in the right direction. Let us know if you have anything else
