I posted on here about 6 months about a problem i was having with the engine after having the injectors replaced..
When cold the van idles fine but when it reaches operating temperature it develops a lumpy idle, I took it back to the Delphi bloke who replaced the injectors loads of times but he couldn't fix the fault. He checked for air in the fuel lines, took it to Ford round the corner and updated the software on ECU, did something with the fuel filter to stop fuel going back to the tank on the return pipe with a ball bearing inserted in pipe (cant quite remember what he did but made sense at the time) replaced injector plugs with new Delphi ones spliced into loom, he said it had something to do with the temperature of the fuel?????
He replaced the injector plugs because when I first picked it up after having the injectors replaced, it started cutting out when you accelerated, I managed to get it back there nxt day and he said straight away the plugs were loose and needed new ones? I did ask if the new injectors were working properly, he showed me his laptop screen plugged into the van and pointed out the injectors firing within the range etc they should and various other things, b as im electrican not a mechanic it made no sense to me so took his word for it.
I gave up in the end of going back and to, and what made it worse was they never needed replacing in my opinion, as the fault I originally had turned out to be a CV joint knackered on the Passenger drive shaft, giving a horrendous knocking sound ( that i thought was a misfire!!) anyway, I had that much on last year I gave up trying to sort the idle problem.
Ive checked for codes and nothing shows up, as I say it only does it when reaching operating temp.. It does have a egr blank plate installed if that makes any difference?
Does anyone have a idea of what it might be?
Im just so annoyed as it ran perfect before!! Also when you blip the throttle it feels lumpy even when cold. I did fit a new accerator pedal whe I first got the van as there was a fault on it, its not a genuine Ford one, got it from Flea Bay. I cant remember if the van was lumpy when blipping the throttle before the pedal change, dont think it was though!
