300tdi auto sluggish

[axeman]

hi...
i have a little problem with my 1996 300 edc auto.... when i start it warm it takes a few seconds before it will recognise the throttle pedal and when it does i can plant the throttle and again a couple of seconds (infact the time it takes for the turbo to boost) then we are off.... it gives me no problems whilst driving only when i stop and try to go again...

i have changed fuel filter, lift pump, water temp sender... if i put a resistor inplace of the temp sender it lifts the revs slightly on tickover and it is better but the fact i changed this tels me it's not the problem.... can anyone help???

my last resort will be to replace the EDC with a good old mechanical pump....

sounds to me mate,it could be the throttle pedel its self,cause that is electronic too,but he price of a throttle pedel,you may be better off converting it,if you can.

[axeman]

you are right with the pedal being electronic, but when it is cold everything works as it should..

What about the temp sender in the head itself - thats linked to the EDC isn't it?

I'm not very familiar with the EDC but I know ot gives you more power than the mechanical pump in standard trim.  That's not to say you can't tune a mecanical to the same or better, plus the injectors are a fraction of the price.

[axeman]

it seems that not many people out there know much about EDC... think i best source a pump...

[Range Rover Blues]

It's a pump, injectors ,the little pipes and a throttle cable.  Can't think of much else that won't become obvious.

[solihull-mick]

Stu as you well know my background in EDC, the system is no different from the high presure side there on, pump works as the mechanical one does, the only electronic part is the throttle control, the only reason land rover used EDC on later auto models was to get the emissions correct, no other reason, best bet as you say, remove the EDC pump, fit a mechanical pump, ive does this in the past with no problems, remove the TDC sensor and bin it, remove the MAP sensor and bin it, repipe as a normal 300 TDI,

But im sure sombody on here will tell you otherwise, but you know who to listen too,  :dance:

Mick, aren't the injectors different on EDC? I know the non EDC ones are way cheaper as I've replaced a couple of sets.

[solihull-mick]

Range rover blues your a correct, the injectors for non edc are ERR3339 x4 the injectors for edc are 3337 X1 and ERR 3348 x 3, hope this helps stu
