Thats very interesting as when the MAF is reconnected the problem is unbearable...... hadn't thought about checking the integrity of the wiring. If this potentiometer arrives over the next few days i can reconnect the MAF and see what happens power wise. You never seem to feel a surge...

Dave, all the wheel bearings are fine, all taken off and inspected during disc/pad change....... not sure if its ABS! how would i know?

Dave, you can feel a 'grating' kind of vibration through the pedal when it happens too!

Def no stones trapped, the noise sounds like when pads have completely worn out to steel on steel, but only lasts for one press of the brakes then its gone! 1. only ever checked it at low speeds as its the first press of the pedal 2. only noticed when the engine is cold as the car has to...

Dave, the problem was always there, hence the investigation of the discs and pads in the first place. The fronts were not too bad but the backs a right state! couldn't see any sign of anything else catching on reassembly it all looked perfect! but something must be wrong somewhere that i didn't...

Ahhh of course!! latest update, these potentiometers are like gold dust!! eventually tracked a second hand one down by emailing around 20 sellers on ebay breaking disco's........ believe it or not only 1 guy actually had one!! £40 waiting for delivery. Not sure this will solve the low power...

ok so i am stupid, it was there........ didnt realise i had to be some sort of circus freak to get at it!!!! anyway i must be cus i got the darn thing off only to find its a seales unit and i cant get into it to clean anything!!

now guys am i completely stupid? maybe! but where is this throttle potentiometer? there are just two cables connected to the pedal, one goes to a bellows mechanism on the inner wheel arch (presumably for the cruise control) the other to a pivot mechanism by the fuel pump, another cable comes off...

Will do giftedboy, got it planned in for Sunday morning along with changing the rear discs and pads :eek:

Definitely worth a shot! I'll give it a go on the weekend and let you know how it goes....

hmmm is that possible?

Looks like its part number STC1734 to me....... £250 on ebay!!! :eek:!! is there any other way to test it to be sure before i part with "mega bucks"?

Slightly new twist guys, i drove it today as i have been with the MAF disconnected and guess what? the missfire and engine light came on!! this is the first time this has happened while the MAF is disconnected. Its not as bad as when the MAF connected but definitly the same problem at the...

:doh: durr yes of course!! reconnected the MAF went through the throttle test as you describe Big Lad.... not a murmour, revs smoothly up and down without so much as a hiccup! Seems to only happen when the vehicle is moving and a small ammount of throttle is applied.

hey, bromsgrove defender, Found roverron products but only do freelander TD4 MAFAM :( tempted to buy another second hand unit and chance my arm again, what do you think?:confused: ..........Mark

Yes the MAF is a large cast Bosch unit, with a flap device in it, probably why the price of a new one is up to £400 compares to a £50 plastic MAF!! Big Lad, tried the throttle thing and seemed fine, i have got the MAF disconnected though, should i reconnect and try?

Hi Big Lad, its Auto

I've got a 96 Disco 300tdi. When driving normal speeds its sluggish but when you let off the throttle or if u just touch the throttle it kind of misses (or maybe goes into 'limp home' mode) and the check engine light comes on, it goes off as u accelerate or back off completely. Think i've...

That would be brilliant, been scratching my head for a couple of weeks now..... worn my hair away!! Dont get home til 6ish though!

Hi all you folk, me and my lovely wife Honey live in Redditch. Just bought a 95 Disco Jap import (for the wife actually) and we love it. just replaced all the discs and pads all round, exhaust, and its now had just about a full service.... feels great to be messing with a real car after years...
