================================================== ===========

Especially when i dont drive (engine started) these errors come up in like 2 min also my MML lights up.

I disconnected my maf and sit in the car (engine running) for like 3/4 min. and it looks like my engine is running smoother then before. INPA didnt catch any errors like above.

I just want to make sure before I spend 300 euros on a maf that it is the cause. And of above errors can be the cause of a faulty maf. Is it a good idea to drive around with no maf connected and look every day if om getting errors with inpa?

I find it also strange that cilinder 6 is doing more work then the others inpa picture 2 any ideas?

Thanks in advance

Bad idea.

You should be using MAF cleaner.

I know (Now)

Your MAF is bad if it runs smooth when disconnected. You may have ruined the sensor with brake cleaner.

You might be able to save money if you buy the Hyundai MAF. It's like $150 new and may fit your model year. The newer e46 MAFs are $300ish.

 

[windmill]

Ok I will check that out! You think its a good idea to drive around for a week without maf and look every day in inpa for errors to be sure?

 

[OrientBlau]

Your fuel/air ratio will be off and you may get a code, but I dont think you will cause any damage.

Here's a thread on running without the MAF:

Thx read the thread. Im going to try it for a couple days see if it runs better and if the errors are gone.

You could damage the engine running without a MAF IF your o2 sensors are shot aswell.

Thought they seem to be throwing a rich code (meaning the engine gets more fuel than it should)
Causes of this CAN be a MAF , but most likely a intake leak between the head and the MAF.

Get a can of engine starter , spray around the intake tract and listen if the engine is affected , if it is you have a leak.
If not proceed with unplugging the MAF and testdriving, if problem persists you should go for a pair of new o2 sensors(if the car runs rich for extended periods of time they will be damaged, otherwise i believe they have about 250k km lifespan)

You have a lean conditon thats causing a midfire find the vaccum leak. Maf cleaner is nothing but a myth I have never seen a car fixed with this snake oil

Will do to test for vaccum leak thx! Drove couple miles tonight with maf disconnected and it felt faster, especially in the lower rpm's. When I came home tonight I sat in the car for like 2 min with engine on. The car was quiet nothing strange happened. I will plug inpa in tommorow see if ive got new errors. Spark plugs wil be changed this week.

Be sure to get the OEM NGK platinums (4 prong). No anti-seize needed and torque is 30 Nm dry.

To actually clean errors from the ecu, I think you should disconnect the battery. You can expect increased fuel consumption with the maf disconnected. And don't use break fluid on maf You didn't specify, but I guess problems started after you did that.

 

[windmill]

To actually clean errors from the ecu, I think you should disconnect the battery.

Im 100% sure that disconnecting the battery will not remove errors. Errors can only be removed with software. I use carsoft 6.5 and inpa.

I didn't know that. How does it keep them in memory? Must have battery of its own I guess.

 

[OrientBlau]

correct. Disconnecting the battery does not erase codes.

Here's another thread on using a Hyundai MAF. Not all e46's can, but some of the older ones may.

Thx orientblau I have the same maf! It's the same and a lot cheaper. Going to hyundai dealer for more info. Yesterday connected laptop, still no errors......

 

[windmill]

Today i went to two local hyundai dealers. I asked them what a maf cost for hyundai sonata 2.5 99. One said 572 euro the other 600.... I placed my order at www.fourgreen.com 127 euro inc shipping thx for the information!!!

Glad you were able to save some money! :thumbup:

if you have an oiled filter it cleans the gunk off the maf...ive done it the old way with a qtip and alcohol and the qtip is dirty after the cleaning
