I've seen the maf sensors cheaper than that mate. You wanna check all your pipe work to the turbo, air box and intercooler too. Plenty of pipe work and hose clips to check!

There are cheap ones on eBay but is avoid them like the plague!

i had a mk2 jtd 1.9, which done similar things to your describing, i unplugged the air flow meter and then it was fine.

With my maf unplugged the accelerator pedal doesn't work at all

Cheeky fiat then, programmed it so it won't work without it lol, the earlier models used to work perfectly left unplugged

Yeah I was trying some wynns turbo cleaner down the intake with the maf disconnected you get no throttle at all, mines a 2007

Mine works fine without the MAF. 2008 1.9 Mjet. I get about 3 drive cycled until the MIL light illuminates.

As said it's probably a combination of EGR, MAF, and MAP sensor. Give them all a clean and see how it feels then.

Try some intake cleaner like described above something may be stuck, disconnect maf, yellow slide plug just before airbox, see if it runs ok like that,

If you have time i would definately clean or even blank the egr off these are a pain, i went through 2 until i blanked

Turns out it was the maf sensor. I disconnected it and it ran sweet as a nut anyway thought I would also check the air filter and that was buggered as you can see from the pictures.... Think that had something to do with the sensor going... Anyway as a temporary measured soaked the sensor in some break fluid and it's made a dramatic improvement tho Im still not sure it's right so will probably just replace it along with the filter.

I also took the egr off and it was pritty much clean tho there was no gasket on the pipe going from the egr to the engine, which I thought was a bit strange as there was one on the exhaust to the egr.. I tightened it up just a little extra incase it was missing :s

Thanks for everyone's help

Blimey no wonder the maf has half given up with the state of that filter. You need a new un there mate!

Seen better days hasnt it lol

Yer tell me about it the mechanic who works at my dads garage was stunned when I showed him :s it's physically bent upwards in the direction of the airflow. I'm in two minds if I should look at a new induction setup or atleast a performance filter

Any suggestions welcome.

Sorry to drag up an old thread but I'm experiencing the same lack of low end power...but I have no faults displayed or stored. Just big turbo lag until 2000 rpm, could it be my egr? Power above 2k is fine, it goes well with no smoke. Any help appreciated before I chuck an egr valve on it

If you get any answers, I'd be interested in hearing about them too, I have a sluggish - very sluggish, in fact the little Sei would overtake and leave us behind sluggishness in low revs at the mo'...

Same here, snail slow!

The forum seems to have been very quiet of recent

Yep, I know, just us at the mo'.. I'm optimistic of more support

Any news, I changed the MAF sensor with another one and no difference...

Does anyone know if the EGR is temperamental sometimes? Any way of proving the function of one??

I unplugged mine and boy... it was not nice - even worse..

Jon

Try removing the the egr and checking the state of it inside, mine wasn't that bad inside but the valve was stuck in one position
