i have a my 99 turbo ppp,lately i have noticed a very slight judder/ splutter/miss fire?from the engine when i drive it this is most noticeable at about 2-3000 rpm,the boost is kicking in at 3500 ish as normal but this also seem a little flat.
has anyone had a simular problem and could give me a few ideas where to start looking for the problem.
thanks

james

 

being a 99 with the maf sensor often failing.. I would suggest you reset the ecu and see how it runs.. if it runs worse then replace the maf sensor..

reset procedure is here

thanks simon
thats what i was thinking but i only got the car last june and changed the maf as soon as i got it,i know they are prone to failure but surely not after 6 months.i will try an engine reset before i got to the dealers for an argument.

 

update- just reset the ecu as described on simons excellent website,no faults to report,the slight judder thing is still there but the car is now flying when on boost,i was thinking could it just something simple like a bit of damp as the car is not used daily and at this time of year problems like that can happen.
any more suggestions gratefully recieved.

 

what fuel do you use and how long between use as some fuel go off..

Simon

 

i use tesco super or total super as thats all weve got down here now,the bloody shell garage closed a week before i got the car. i put petrol in it once or twice a fortnight.
i work 7 day shifts so gets used one week then usually stood for a week.

 

that should be okay..

might be worth changing the plugs

 

ok i will try that then what plugs shall i get?thanks for the advice.

 

standard plugs are ngk pfr6b and you must gap them to 0.7mm

 

thanks mate
