1.6 4afe Engine Intermittant Fault

[metts]

I have a 1.6 estate with an annoying fault. When the engine gets hot it runs on three cylinders and then picks up on four again. It does not always do it. I also have a 1.8 so I have tried to eliminate the symptoms by swapping parts over. I have swapped the H.T leads and a vacuum switch (which is situated on the bulkhead) over but the fault remained. I checked the resistance of the injectors and they read 15 except one which read over 100. I thought I had found the fault as I also checked the electrical supply to the dodgy injector with a test light and found the supply to be good. I swapped the faulty injector from number three cylinder to number four to see if the fault moved. It did for a while but then number two injector started playing up. Can anybody help please.

I have now cured the above problem by fitting some second hand injectors off of a 1.8 Carina. The injectors are colour coded so the fact they came off of a different engine did not matter. £25.00 for four injectors and the rail - job done.
