Maf sensor

[Will]

@savage bulldogs I haven't checked the pipe work for any leaks, although it has just been in the garage to get checked over, serviced etc the guy at the garage said he wanted to eliminate it being serviced and that before looking into anything else to do with the idle so I don't think he would of gone as far as checking the icv or maf but may well of checked the vac lines etc while being around that area (there's **** loads and I dunno what's what lol so not sure I can do that without someone being there and pointing things out) 

he also mentioned the air filter is crap and I can tell it looks in poor condition but could that be the cause of this when coming to a stop? 

Plugs and that would of been done in service so there all good and again I'm new to turbos so what do you mean by holding boost? It certainly kicks in nicely and feels smooth with out lack of power 

also I forgot to mention the abs flashes sometimes when driving at low rpm and it judders a tad then runs fine when it's not flashing, I read because of the wheels, brakes and it being wider than standard could cause this? 

It all seems linked in some way and it's something silly causing it to run badly at times as other times it's really smooth, when I start it when it's cold the revs are pretty much on 2000rpm and then earlier when I got home and parked her up again the abs started flashing and started running rough on idle and making some tu tu tu sound haha sorry for the sound description but it's the only thing I can put to the sound, lastly when I reverse it seems to hold the idle nicely if that's any help

Anyone else got any thoughts and/or answers on this?

Most of the small bore pipes in the bay are vac lines . Just check for perished bends or joins and if they've been replaced with aftermarket ones (normally coloured and not black) make sure if there bent they're not kinked or loose .

Follow the pipework from air filter , through the turbo to the fmic pipework all the way to the throttle body. Check for pipes rubbing on the bodywork (which can wear holes ) cracks on the bends and that the joins ain't leaking .

A clogged or poor quality air filter can "strangle " the air flow and cause hunting idle and lack of power .

By "holding boost" I mean does it reach full boost and hold the same pressure . As if you've got a leak it might only show up under higher pressure causing the boost to tail off or not reach its peak pressure at all .

I'm not to sure about the abs light as mines to old to have such luxury lol

Thanks mate much appreciated, I ordered a new icv gasket so I'm going to give that a clean and when I do I'll look over the pipe work etc.

what do you recommend for cleaning it? I have found a post of someone explaining how to do it and they say people have used fuel and all sorts, surely there's some sort of spray or something that'll be better.

It's holding boost fine but as for the air filter I'm definitely going to get a better one in the near future, but for now I pretty much have it down to an art, when I come upto lights I'm having to brake with most my foot while putting a bit on the accelerator so it doesn't dip then when I come of the accelerator it'll dip once maybe not even that and sit at idle, again it idles when in reverse haha literally confusing me so much but I reckon it's something petty (touch wood)
