Mondeo Rough Idle Runs But Cuts Out

[john34]

hello all

i have a problem with my 06 reg 2.0 130 mondeo

it starts with no problem but it goes all to pot ie stuttering and trying to cut out sometimes it will let you rev it with no problems apart from a slight lumpy bit to it you can drive it and it has no problem getting up to speed

when it idles its verry rough and cuts out

this is what i have done so far

took off egr valve cleaned it not much in there

took off inlet manifold cleaned it not much in there

new air filter

cleaned maf

fault codes i have found

stored

p0100 power train maf sensor ckt insufficent activity

p0251 powertrain injection pump fuel metering control "a" malfunction cam rotor injector

pending codes

p0409 no defernidyion

p0404 powertrain exhaust gas recirculation egr open position performance

what else can i try

any advice is very appreciated

thanks

john

fuel filter??

[john34]

Hi thanks for reply

Not done fuel filter yet as if it is the fuel pump and I put new fuel filter on

I have been told I will get silver peces of metal in it and

That fuel filter will be no good but if the engine runs ok if I rev it I cant see it being the pump

when you cleaned the egr did you get a vacume on the valve to see if it operated ok, it could also be the injectors playing up,either by losing their code to the ecu or one injector not firing right, these can be checked by a leak of test.

Check camshaft position sensor too, if it's dying it doesn't speak to the ECU properly and the timing can be advanced or retarded when it doesn't need to be, causing lumpy running.

Thanks for the replys

Egr I used the pipe and gave it a sucking lol and it opened

Camshaft sensor how do I test it and where do I find it I think it's on the gearbox side

I shall try and check the timing if I get chance

Thanks again

hi

even tho its raining i have done the following

replaced fuel filter with a ford bosh one

spray carb cleaner down air pipe

cleared dtc codes

forgot to say the batt light is allways on

same as before now i get

p0404

p0622

any help and where to look would be great i will get a nut on the glow plug

i brought this car as having a problem but i think it has had a new clutch as its very sharp so may be a wire loose or a plug not in right this is a much as i know about the car

thanks a lot

Mondeo mk3 2.0 tdci (53 plate) car stopped out of the blue, code for cam sensor detected which was renewed. Car started but had to be cranked several times before starting ran ok but problem still there when starting. Changed ; crankshaft sensor, fuel filter, a.g.r. valve, mass air flow sensor and problem still there even though car run fine once started. Solution.... Was the aftermarket cam sensor was not sending enough info to engine control, changed cam sensor to a dearer o.e.m cam sensor and now engine starts and runs perfect.
