Help before i put a match to it!!!

[Moz_Goodwood_309]

hiya all

my saxo has developed a very annoying problem, when its cold the orange transmisson light comes on the dash then flashes for a few seconds and puts the car into a limp mode

if you turn the ignition on and off it will come out of limp mode but the light is still on, it will do this three or four times then stops once the car is warm (but the light stays on)

on the diagnostics machine it comes up "random missfire on cylinder 4" id imagine its not mechanical as surely it wouldn't clear it just by turning the engine on and off?

ive took it to citroen and they were as handy as a bag of a*seholes they tried swapping the coil pack but with no joy

its getting expensive now as we've tried a new coilpack, full service (all filters, oil, plugs and leads) new idle valve, new crank sensor and a new head!!!

im sure its something minor but its costing a bomb trying to find out what it is

its also "lumpy" on idle but it stops doing that once the lights stopped its flashing routine

the car is a 2002 "52" plate phase 2 vtr, with the 3 plug ecu any help would be much appriceated

cheers

does it misfire and lack power ?

[Moz_Goodwood_309]

yeah a few times then clears if you turn it on and off, but the light stays on

took the battery off for 3 hours today, as soon as i connected it back up the light was on again and when i started the car it did the same thing as before!!! :wall:

any more suggestions anyone???

Either a faulty ECU or a break in the wiring to the ecu.

does it have to have the same numbers on the ecu or can it be any ecu off a vtr and of the same age???
