My 2005 tdci 130 mondeo has developed a fissfire it started off as kinda a flat spot under light throttle (which is all it needs normally ) but seemed to be ok under heavier throttle but there did seem to be a bit of pinking however the next morning it took 2 attempts to start and was quite lumpy on idle , sounds ok when you blip the throttle but as the revs get up a bit it starts to sound like and old Di , rather rattly and it is throwing out blue smoke from the tail pipe , sounds like the timing is out but I believe the timing is done electronically ? any ideas before I start throwing money at it ? Incedently my cheapy code reader is showimg no codes !

 

start of the dreaded injector issue possibly

EML light on?

 

ive had it before where the dmf has caused the engine to missfire as the cps thinks the engine is in a diffrent place to where it is

 

There are no lights on .

 

Tried the cam position sensor in my mates mondeo to rule out that , came back and put it back in and took the car for a run the blue smoke cleared and it started to run quite well for a wee while until it went into limp mode with the glow plug light flashing code reader showed up p0251 , cleared the code swithched off and resarted it and gave it a bit of a welly the glow plug light and engine management light came on again p0251 and N/A for the eml , rebooted it again and it now stutters like its away to cut out then goes again !

 

injectors probably need re coding.

 

Just to update , dunno how I managed as obviously the mondeo is diesel , my transit is diesel aand the wife's shogun is diesel but I managed to put Ł50 of petrol in (still think it might be the garages fault ) drained the tank last night took the injector pipes off and emptied out the common rail put a new filter on and put diesel in the tank and hey presto it runs fine now , when I discovered the error I reaserched it on line and was gutted , thought the engine , pump and injectors would be fooked but so far so good , I reckon I must of done some where in the region of 35 - 40 miles with the petrol in and was surprised it was running all be it badly !

 

Fingers crossed its ok mate, but i got a feeling the pump wont last long

 

my instant reaction to that would also be to throw in some two stroke and put some more diesel in or mix 300ml in a jerry can of diesel and add that, it will jkeep it lubed and clean the injectors
