Hi

I was wondering if anyone could shed any light for me on this one, i have a ford focus 1600 16v in at the moment with the fault code p0303 cylinder 3 misfire detected. I have replaced the spark plugs first as wrong ones fitted also replaced coil pack and ht leads fault is still there, if you pick the revs on the engine up to 2200rpm u can feel the miss and poor acceleration any body got any ideas please

Thanks Andy

Try switching the NO3 injector to another cylinder and see if the miss follows ?

Failing that, carry out a compression test.

Has it got the correct calcium battery fitted?  [Yes; seriously.]
