i know this has probly been asked a million times before but.i have a v reg uk turbo wich seems to hesitate/chugg at around 3000rpm at light throttle.i you floor it it passes.it has the dreaded pipercross filter on it which i will be changing for a k and n.had it serviced bout 3 months a go with new plugs and have cleaned out the solenoid.feels worse on the motorway at around 70
and feels underpowered.how much for a new maf £80? and do i need to have the ecu reset when i fit it? other things i thought of were leeds and coil packs but these would just stop completley????? any help greatly appriciated

could always try cleaning the maf..

could be the lambda sensor , unplug it and see if it dissappears (but not for long)

this is just what i have read on other threads

where is the lambda sensor and what bdo i use to clean the maf?

 

As the maf is known for ending engines, it would be the last thing i would try and clean. Lose the pipercross and fit a k&n followed by a brand new maf. While you are waiting to get this lot sorted, i wouldn't drive the car anywhere.
Lambda is in the downpipe

 

has been doing it for a month or so not really bad. but is our only car so will get it sorted this week just have to take it easy.doto i need to reset the ecu?

 

ok best not try cleaning the maf ... just read somewhere that you could spray it with carb cleaner to try and clean it ...

as said the post i put up was only from what i have read ..

when you say replace the pipercross filter for a k and n and take it you mean panel filter ???

 

I had a k&n cone without issue for 5 years on my MY99, i did however replace the maf every 2 years regardless. I understand that cleaning the maf if possible with the method you have mentioned but like i say, the maf can end your engine - £80 versus £3k +
