Hi

This vehicle has an intermittent misfire has been back to fords a couple of times but they cant find any thing wrong. New HT leads and coil pack have been fitted (genuine) no codes in eobd or man specific could it be a software problem ?

Hi Paul,

This sort of thing annoys me and I have heard it so often. If Ford have built the car, then they should be able to fix it.

Anyway, assuming the plugs are OK my next step would be to suspect a valve problem and would change the oil with an engine flush. I also use a can of Forte Gas treatment and then let the customer have it back for a week or so and see what happens. If problem still persists and assuming no DTC's are recorded, I would send the ECU away for testing.

I hate intermittent problems!

Regards

Pete M

Hi , as you are aware ford's are usually pretty good at logging fault codes for misfires .That engine never gave any great problems with sticky valves being a jap designed head .
Gut feeling is it's going to be something obscure so get it back into the dealership or find another one , also ask for the field engineer to come out and check the car .
