Fuel Problems

[dayne]

Hey guys,

I have a r33 RB20E

I'm getting 250kms per tank on ultimate, and 300kms per tank on optimax, just had new plugs, new oil, etc. I only rev out gears occasionally, and i cant seem to work out why my fuel economy is so damn bad!

Ive put up with it long enough, but now its past a joke!

I only live 5-10kms from school so it does do a fair few cold starts a week...

Can someone suggest how i can go about fixing this? and getting a bit more kms out of my tank, i dont have any complaints about the car bar that. I was thinking dyno tune, but what else is there?? and is this even possible with the stock ECU. Also, is there anything i can buy aftermarket to make the situation better? can i advance timing etc??

Thanks guys....

hmm... 250-300 to the tank is quite poor.. specially in a 2L car...

I wud recommend maybe try resetting the ECU? (there are threads - try a search)

clean the afm? but yeah a dyno sounds like a good idea and will save u from mucking

around - check the AFRs and see how it goes.

keep us updated man.

Sounds like a possible faulty O2 sensor or AFM. Thats ridiculous consumption! I thought mine was bad but noway near that bad.

yeh there are a few owners on sau....

[dayne]

Alright, so how do i go about doin sumthin to the o2 sensor, and how do i know its that? and the AFM, how do i clean that??

[Eug]

Search is your friend, so click here..?

[gatty]

a rb20E or a ca18 skyline wouldn't be too fast...

and mate some people say to spray the sensor with contactor cleaner - whereas I recomend circuit board cleaner as contactor solution does leave a residue

[dayne]

rb20e is a little faster then your 100kw corolla, civic si,vti, etc!

not the fastest thing, but when youve just turned 17 i dont think you'd really care.

i'll try that, and a few other things today n let u all kno how i go.

CA18 was R32 (GXi model) only, thankfully! I think a whale would be a bit too much for the poor little 1.8L to cope with....

R33 GTS (ie no '25') has the SOHC RB20E for reasons best known to Nissan.

New o2 sensor in, Car is much better.

Thanks guys:)

[gatty]

no worries mate, not putting shit on your ride - just was amazed they'd put a 20E and not even a DE in...

[gatty]

BTW - you say your car is a 1995 - but it has the 20E in it? WTF

btw it looks nice mate

[NJR 34GTT]

It is quite nice in the flesh too. Seen it in Woden a few times.

Good to hear the O2 sensor fixed your problems to an extent.

[dayne]

Yeah, now i just need a few more things and it'll be sweet:)

Yeah its a series 1.5 R33 skyline with an Rb20E

Pretty strange i thought too, but it'll do for the time being, might even turbo it, but i dont think it'll be worth the hassles, just sell up and buy one already done!!

Thanks again for all your help!!

Anyone needs a new sensor, repco sell them i baught a ford EL one, got it for $85!

[wilmee]

hey dayne is the new sensor improve a lot fuel economy? becoz i think i got same problem as you, may be not that bad...but i am not happy with it.

[Pva_Glue]

Let it go Getty!!! just deal with it! R33 with RB20D ok?

and Dayne

add to the FAQ (sticky thread in N/A) maybe it will be useful for other people

cheers

According to the following site. the RB20E r33 is a "GTS urban runner" or "GTS urban runner S" =)
