Once again i call upon the superior knowledge of this forum for an idea of what's up with my Discovery Series II!
I internmittently suffer from a lack of power, almost as if the turbo is not working. The engine will rev to 3000 rpm but then just goes flat & I can't accelerate any more. I also notice that I lose speed on hills when this condition occurs. There doesn't seem to be a misfire, there just isn't any power. It happened today on my outward journey but cleared when I was on way back & it all seemed to be fine again.
I replaced the air filter a few weeks ago so it should be breathing ok. I'm stuck for ideas, anyone help?
 
Thanks, what am i looking for on the red plug? signs of oil?
With the air flow meter, I assume this is a straight swap & not something I can test without a diagnostics tool?
 
Try unpluging the air flow meter,and going for a drive.Ecu will run on default settings,so see if it improves,if it does it probably a f*cked afm.
 
Would seem to be connected to the MAF. Disconnected as advised, went for a drive & what do you know.....pulled cleanly & revved in every gear! Thanks for the suggestion Jon, it's much appreciated.
Anyone suggest where I can get a replacement MAF without mortgaging my house?
As I have owned the car 8 weeks & had a job to do every weekend! I have to assume that this is setting the tone for Disco ownership & my weekends will now be taken up working on the car!
