off two cylinders

[ctm]

firstly would anyone have a cure for a pr06 being off on two cylinders 2&3.i think it may be the coil as i changed it but the problem was still there at low revs in third gear.i changed the plug leads about and tried to swap the leads into the fuel injectors but no difference.when leads 2& 3 were off the car run the same but if either 1or 4 were removed the car stoppedwhen above 5500rpm the car is fine.
could it be the fuel pump or maybe the alternator as i checked the compression on each cylinder and they are fine. any help would be appreciated as i am hoping to race next friday sat and sun at anglesey.is there any way of testing the injectors, coil, alternators, etc
secondly; what type of coil is it. peugoet or alfa i am told but more help would be good.

i have a wiring diagram for an SR3 that might shed light. if the PR6 uses similar electrics it might help if you need it.

if its 2 cylinders it might be a faulty connection to one side of a coil... the SR3 uses a "lost spark" process and 1 connection to the coil can affect 2 cylinders.

thanks for that. i have it down to a faulty coil or a fault within the ecu which i am getting remapped at present. then i can rule it out.
