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 :y

Checked the timing? Dead easy on 2.2 :y

I have not as yet Tunnie . . . could be a real possiblity though . Is there a guide on here to check this ?
Car does not seem to misfire constantly though :-\ :-\ :-\

Have you not heard of copy & paste? :D

Just spoken to the owner on the phone. He now says the car was "OK" when he first got it back from having the the belt & W pump done for a
week or so . But then started being down on power & hesitant .
Car ticks over at a really steady 850 rpm but will then sound like it is missing & revs drop slightly for a split second & then return to a steady
850 rpm . When this occurs the EML will come on & stay on until codes are cleared .
If timing was out ,would only N0. 2 pot show a detected misfire ? or would it show on all pots? :-\ :-\
Note: garage that done the previous work must be right muppets if the state of the original cam cover gasket is anything to go by. Was in several
pieces & stuck back with what looked like a whole tube of black sealant . May not have been them of course but owner has been taking
the car to them for over 2 years ::) ::) ::)

4-pot should be around 700-725rpm steady
