Welcome aboard..,

many things could cause this issue, MAF/fuel pump/dirty fuel filter/stucky injectors/coils/plugs,,

better if you can diagnose the car, codes will tell>>>avoid losing $$$$..

Should check fuel pressure

But it does sound like an MAF, need a scanner and read the actual values of it

DRBC43AMG

As Zayed mentions, your problem could be a number of different things. Best bet would be to scan and read any error codes. You can always try disconnecting the battery for 30mins and see if the problem disappears. The only drawback will be your need to reactivate the power windows, roof, etc. That is not difficult and only takes a minute or two.
Come back and tell us what you find... We are always interested

PS Has the vehicle been serviced recently: oil + filter, plugs + wires, intake filter, gas filter, etc.?

TYPO I meant it has , 120k mileage, and every time i hit the gas pedal to the second click of it, it doesn't want to move like a regular car, just sounds very aggressive but no pull at all, no power.
BUMP BUMP help me out, i tried REDLINE injetor cleaners 3 times but didnt help out.
should i change the MAF? and what is a Tranny Remap.

Bad MAF could do this, but not sure..!

Do you have a chance to diagnose the car..?

ZAYED,,

hughc43AMG

Don't go with these aftermarket copies, just get OEM/Bosch units only,,

aftermarket copies = useless big HEADACHE..

ZAYED,,

DRBC43AMG

Agree 100% with Zayed. Use Bosch original MAF only. It may cost à bit more, but you will rarely have à problem again. I just did mine recently and she pulls like an express train B-)

KJI3jflarryfe93

there are MAF's sold by VDO, these are good to I believe

hughc43AMG

Alrighty, ill look into the bosch MAF., ordering from ebay good?

If you want to save some coin, you can use pliers to unscrew the security screws and take the actual sensor out of the housing. On the side of the sensor there will be a Bosch part number. Look up that number and you can buy the sensor by itself. They used that same sensor in several cars including vw and is a lot cheaper.

I believe that I still have my old MAF hanging around in the workshop. Let me check this afternoon and I'll get you the sensor #s

DRBC43AMG

OK peeps, I removed the MAF sensor using this tool which worked fine for me (see below).

ID numbers on both sides of the sensor, so I made photos of both.
Hope it helps

Super B

Right on DRB thanks for that, yeah it's the f00c2g2025 that you want If I remember right. The BMW's use a 2029. Hopefully saves the guy a couple bucks and I agree with using Bosch only.

hughc43AMG

So i should just replace the sensor only?, should i just get awhole new MAF too just incase its clogged.

Super B

Well, it really can't clog. The housing for the sensor is just basically a tube with a plastic screen in it to smooth out the air across the sensor. The sensor slides into the tube and screws in with two security screws. (To remove it you have to use the bit like DRB used for a pair of pliers if you don't mind scratching the screws a bit)

Then it slides in but make sure you have it facing the right way.

<p>Alright, so buy me a new Sensor it is.</p>

Amazon got them as well:



ZAYED,,

Well that sucks, I looked for the last hour for your sensor and looks like the days of buying it separate from the housing are over. It didn't used to be that way. But I guess it's probably easier to sell the whole housing with sensor.
