erratic idle and loss of power

[anya]

Hi evrybody, i've just joined and need help!!! I have a golf gti 1.8t (150bhp) and i have recently been experiencing erratic idle and loss of power-power is not continuous and jerkery especially in 2nd gear. I have just replaced the oil air flow pipe since it was split-and thought this may have been the problem-but the problem is still there. i was told by VW dealers that the air mass meter is usually the problem.

Has anybody come accross this problem and is it worth replacing the air mass meter

Many thanks

LOL id alread presumed from your thread title what the problem may be and your description narrows it down more or less certainly to the MAF (mass air flow) sensor. these are notorious for failure on the mk4 range, especially it would seem on the golfs. the main problem being that the air drawn through the system passes over this sensor, no matter how good your air filter is, it will still collect crap over time and becomes clogged up.

let me post this up for you : (thread located at https://www.vwaudiforum.co.uk/forum/s...?t=3983&page=2) :

Just a quick subnote,
Last night I cleaned my MAF sensor, using an electrical solvent (i.e used by sparkies for cleaning circuit boards and the like) to clean my MAF sensor, the car is beyond recognition, smooth from startup, starts pulling a lot stronger from 1500rpm and a lot less reek in the rear view,

Surprising bonus, an increase in economy, from 40 ish for general running to and from work to 48, that's a big differance, wish I'd got round to it sooner.

Engine was always smooth, but now it's a whole lot smoother, I would reccomend checking and cleaning to anyone who thinks thier motor isn't running just quite right.
The security screws can be removed with a decent pair of mole grips, but remember not to touch th element, use an aerosaul spray theat will just run away, and look for one that doesn't leave a residue.

just another note, give the above a try, its always worth a try and substantially cheaper than buying a new sensor, let us know how you get on
