hi guys been trying to sort out an local old fellas 03 plate 2.2 petrol omega.
Feels down on power & hesitant with a intermittant misfire with EML on .
First job was a cam cover gasket change as plug wells were full of oil & a breather clean
There also seems to be an intermittant quite audible "clicking " noise from around the top of the engine /coil pack area a bit like it would sound
when HT is shorting somewhere .This" clicking" goes faster & slower with engine speed Could this noise be from a defective injector?
codes read P 0170 & P 0302. Then cleared these . . EML no longer on but after a short trip returned .
Replaced spark plugs . . still the same .
Replaced coil pack as No. 2 pot coil showed signs of rust etc. underneath .Rubber spark plug connector was also split
Re cleared codes . . EML out . . . but came on again after a short trip.
Same 2 codes keep re appearing . . 0170 fuel trim malfunction & 0302 cylinder 2 misfire detected .
Owner says car has not felt the same since he had a local garage replace the cam belt & water pump .
Any ideas where to look next

TIA Al
