my sir kills too much gas i only get 160km on a full thanks oil is always good air filter is clean and it still kills gas...my plus are black and white could that be causing it?

160 on a full tank....thats rediculous. something is very wrong with your car for sure. when was the last you did your tuning? are you sure your car is not leaking gas cuz even with the worst of maintenance....i would argue that a civic is capable of doing better than that on a full tank

and black and what plus or plugs?

toofastcrxx

there black and white the sparks plugs

chris_si98

you're all over the map. My best recommendation w/o a GOOD explaination, would be take it to a shop. Could be anything...

Looks like you got a crx with a swap, so for all I know you have the wrong ecu in there and the ign. timing is way off.

i bought a 00' civic sir

chris_si98

ok.. so what have you checked/done?

160km per tank is ****ing brutal. I'd imagine your car stalls alot?

toofastcrxx

no...i shift at 3,000 rpms all the time and my spark plus are white and black i think they are done could that cause it?

imported_starboy869

I would think you need a major tuneup. Spark plugs white & black?

Which one?

When was the last time you checked the air filter, pcv, timing? Are you using 91 octane fuel?

95 R-81 Cx

Does your car sound like a diesel and smell like gas?

I don't even think your car would run if it was injecting 4 times the amount of gas it's supposed to. Either you're leaking it, or someone is stealing gas from you wherever you park

did the car pass emissions testing?

Dammmmmm 160km on a full tank.... but yea how about a 98 Gsr on a 99 civic 350-400km? Is that average? or is that low?

imported_Cablerat

My 98 GSR gives me easy 450-500km shifting average 4-5K. and cruisin @ 140km/hr

Its ur O2 sensor! , and is ur check engine light on!?

chris_si98

what makes you think its the o2 sensor?

imported_t_dot_SiR

(1) someone stealing gas from your car
(2) how big is your tank? don't tell me your gas tank is like 15L in size and that is still consider a full tank haha
(3) your gas tank is leaking like mad!
(4) ur fuel lines might have leakage somewhere
(5) time to sell your car for a grand!

i can get 500+ in the winter with my 00' SiR and thats with the ocassional stop light to stop light beating time to time.

I would almost say it's nearly impossible to get that bad with an 00 SiR.

Something seriously wrong, just like what everyone else has said. You have a leak or something. It's going somewhere. Is your fuel guage working properly?

imported_Cablerat

I find it hard to believe that you would not be able to smell a fuel leak. Gasoline odour is very prominent and for the amount this guy say he gets to the tank, he must have a major leak.

Perhaps he messed up and wrote 1 instead of 2 or something.
Let's wait for this person to respond.

My hatch w/ the b16 swap was getting max 220km to a tank at one point

your hatch was also smoking like i've never seen a car smoke before....hmmm....wonder why?....cough***too much oil****cough

imported_Moe_Mentum

Man did you buy the car like that or did it just start getting really bad fuel mileage? If you just purchased the car and it was certified and E-tested I would definelty go back to the buyer and mention it.
