Running Problems

[m14caa]

Hey guys just thought i would ask to c if asnyone could shed some light on the subject

For no apparent reason my glanza decided to fuck up the other day by just running on 3 cyliders, i have changed plugs, leads, dizzy cap and rotor arm and it was fine but ever now and again it drops a cylinder again, can anyone give me any pointers on what else to try?

I have had a engine managment light on aswell but that has been on a while now before any of these problems, i have done a pressure test on a the cylinders aswell and they seem fine,

hope sombody can help

thanks
Macca

check down in all the spark plugs, these cars tend to get a bit of water in through the vent which then runs down in past the ignition leads. Happened scooby there few weeks back, had water in the 3rd plug closer to the dizzy cap.
