on my clio it's single point injection, and literally it's pumping loads of fuel into the inlet, anyone heard of this on anything else?

i've had multi-point systems have a faulty injector and cause a missfire but never worked on single joint before?

any advice?

 

It can happen....but is it stuck open mechanically, or stuck open due to incorrect control from the ecu/wiring ?

 

They can, but lots of other things can cause this too.

yeah see thats where my diagnostic skills draw a blank!

it's pretty basic on the clio with just a map senser, throttle position, iscv, temp senser, injector, crank senser.

tps, map, iat & injector is all on the injection unit itself so am going to replace that first and then map/ecu.

vacuum pipes are all good, wiring appears all intact and good, any further advise?

get the injector tested that would narrow that down or could it be the automatic choke thats fucked up? and is on all the time?

 

To see if the injector is mechanically sticking open you could disconnect the wiring/plug to it then run the fuel pump (short the relay/direct feed to pump). If it is mechanically sticking open there will be fuel flow from it.

As said above though it could be a number of things that are causing it to overfuel.

 

found the problem, ecu full of water!

 

Well, it is French after all !!!!!

 

cars a bastard piece of shit, broke down again today, fuel starvation!!!!!!!!!!!!!!!!!!! :blub: :blub:

one extreme to the other in a matter fo days!

 

Did the ecu not have his diving gear on then!!
