Hi folks,i have today spent nearly 3 hours at my mv6 and it still nae better.I have cleaned throttle bodies,taken of plenums,cleaned all the breather pipes,checked all the vacuum pipes,cleaned spark plugs,checked all cables and connections and it still has a mind of its own,when i touch the pedal it rises to around 2000/2500 revs and sits there for around 10 secs then drops to idle at 600rpm,anyone any ideas what this is as its doing my head in!! when slowing down to road ends it revs up and when changing gear it sits around 3000rpm,seems like throttle sticking... i have only acces to snap on solus which doesnt really give any depth in live data,it drinking the fuel too... help me please before i go mad and sign meself in!!

throttle position sensor is a possibility..lets see what other members think ..

[hoofing it]

i'd say icv :-/

You didn't mention having cleaned it  :-?

[Smooth]

no icv or egr,what is the electrical unit on the side of the throttle body,is there anything mechanical in there to be cleaned?? Not showing any throttle faults etc on computer,only fuel trim fault but this is due to cats being removed

[unlucky alf]

is it an air leak somewhere, or perhaps a dicky non return valve for the servo :-/

[Broomies Mate]

I'd be using a family size can of carb cleaner under the bonnet while it is idlin'g.

Sounds like an air leak to me.

tps..

classic air leak symptoms in my experience, but then i've no experience of drive by wire issues, no fault codes i take it?

How far down did you strip it? need to go down to the seals under plastic wedge in the v and work back from there if there's nothing obvious, but sounds like you've already done that, back of the main vac pipe from to plenum is classic for waring through on the air con pipe next to it, any hissing dieing out after the engines stopped? any hisding at all come to that?

I'm gonna go round her today with carb cleaner,see if that makes any difference,does seem like an air leak,would there be anything sticking in the throttle position sensor,its the only thing i didnt open,any mechanical in there that needs cleaned??

tps can not be cleaned.. its an electronic part..

cheers

[Smooth]

No difference with carb cleaner sprayed round her,whats the vacuum box at front of vehicle down at pulleys,2 vacuum pipes coming from it,would it be anything to do with this??

[Smooth]

Just also noticed that it doesnt do it when cold,after 5mins it will tho,your bound to be getting sick of this but me having a blooding nervous breakdown here :-/

More news today folks,missing and backfiring now,coming up p0120 and p0220 faults,throttle postition switch a circuit low and throttle postion swtich circuit high,could it be the sensor on the tb's?? also coming up random misifire on all the cyclinders,major loss of power,also tried disconnecting the airflow but no different... anybody please?? really doing my rag in now
