hi everyone ive basicly got myself another Subaru sport 2.0 awd basicly

in low revs pulling of and what not there seems to be lack of power and judders if i give it higher revs it goes as it should just wondard if this is a common thing ( hope what ive typed makes sense )

been to a garage today and they seem to think it could just need new plugs and leads ? any help of people who no these cars well would be much appreciated and the speedo sticks at 40mph but that maybe a new thread along with a few other issues. . .

try the maf sensor mate. Mine is faulty and has the same symptoms. I tried cleaning mine at the weekend but messed it up and now it runs like its hesitating as low speed/revs.

Failing that, give it a service including plugs, leads, fuel filter etc.

Really, where is the Maff lol, 02 sensor fella Ive recently had this issue with a mates car.

COBRA666

so it could be the 02 sensor??

as you may of guessed im not mechanicly minded lol, anyone in the nottingham are who could take a look to give me a better idea

COBRA666

fingers crossed the new lambda sensor cures it when it comes, and it stops driving like a bone shaker talk about judder lol

if you're not used to driving an AWD car, you may be surprised to find that there is a lack of power from a standstill compared to 2wd cars. If it's extreme or juddering then there may be some other issue but if it's only slight, you might just have to get used to it.

i had one a few years back mate it certainly didn't judder like this but i do no what you mean, along with the juddering power loss its drinking fuel like i do ale on the weekend and that ain't good

well they do drink a lot of fuel, but yes if it's juddering a lot then there must be something amiss, and if it's using even more fuel than usual then maybe it is MAF or lambda. could also be a bad boost leak (not that there's such thing as a good boost leak, ).

Yes ECU will want a reset, is this one working? or can the mechanic see it on diagnostics ?

COBRA666

its not been on a diagnostic and i had it fitted at a tyre/exhaust centre
ECU reset - battery terminal of press brake pedal a few times method?
