My 18is is consuming way to much fuel...

[MTD]

Haven't done a full tank since he cleaned the errors from my ocb so I still don't know for sure , but he did it when the other one was halfway through and that one got 10,7l/100. Better, but I still would like to get much better out of a m42..

Any update?

Well i talked to my mechanic and did just that, its in the exhaust shop as we speak, should be ready today ;)

regarding the fuel consumption, more news... My mechanic used the machine that detects errors in the ocb, and discovered that it was accusing an error that wasn't wiped out previously. So he wiped it all. Let's see if it makes any difference

or cut it open on the top, remove the catalyst mesh and weld it close again.

but i can´t say if that´s going to affect your engine performance & noise or not

How hard is the law about catalysts in your country?
For me it isn´t required to have a catalyst, so i just removed it.
this will free up some horsepower too :)

offcourse you can replace it. but those things are really expensive

they are somewhat hard. What i could is, like my friend did, take of the cat and put a resonator in its place. It disguises it somehow ahah

He said it wasn't much, just that he noticed it.

BTW, is there a product maybe to clean it or something, or do I have to get a new one?

You'll need to replace it.

If your catalytic converter is restricted it will definitely impact your fuel mileage.

Hey guys, so the car is finally back from the mechanic today. It was currently doing 12.2l/100 (before mechanic). Things that were done:
-New control arms
-New bushings
-New wheel bearing for front left wheel
-Lambda sensor got cleaned up and fixed, wasn't working properly
-other sensors all around were "touched up" and overall priming of car

Things he noticed that will need fixing:
Somewhat urgent: front right shock, almost gone
Not so urgent : the catalyzer is getting a bit obstructed, not much right now but still

Also right now the alignment is fucked up, given the work he did.

So... Let's hope the fuel consumption drops! Filled a tank today, will report when I have results!

Hope it works out for you. I would think you would notice some pretty nasty shaking if they were worn enough to cause much mpg loss.

Yeah it does shake. I don't know what is considered "nasty", but at high speed turns and bumps i can hear it rattling. If i drive "normally" it doesn't rattle

^ that's a control arm, very important component to hold your alignment. In my opinion you should not have had an alignment done with a worn out control arm bushing/ball joint.
With that said, it could also impact mpg.

When i got it aligned i did not know i had a problem in the control arm. Well,lets hope that it improves my mpgs when i put in the new ones *fingers crossed*

check your alignment. I just put in an e46 rack and drove on it for about 100 miles of mixed city/highway. went from 29mpg down to 20mpg. Car felt wayyy better after having it aligned and mpg has gone up.

Alignment is not the problem, i got it aligned about a month ago. Will also do it again in 2 weeks when i get the new wheels. What i do have is a slightly loose "suspension triangle" (i don't know how to say it in english right, but it's this part: http://i.ebayimg.com/00/s/NDU4WDQ1OA==/z/lh4AAOSwMmBViAI5/$_35.JPG)
But that will be taken care of next week as well, i already have the new parts with me. I suppose that shouldn't be the source of the fuel consumption right?

Does your heater blow hot air or simply warm air?

It blows hot air
