My 2003 has an intermittent misfire in cylinder 2, EWL comes on and pollution error on the little screen. My cheap ELM327 shows P0202 code. When I clear the code the car runs fine for 30-40km before the same thing happens. Then repeats. Interestingly this only started after I had the cambelt changed - mechanic assured me that this is coincidental (Google search suggests this is far from common). I'm leaning towards a faulty coil in #2 and I know I should get a full diagnosis done but trying to avoid the NZ$200 fee for that.
Misfire kicks in around 2000rpm, fires on all 4 cylinders above 3000rpm.

It would be easier if the misfire was continuous!
Any help would be much appreciated.

Indeed - thanks for the prompt ; 2003 EH, 2lt petrol, done 181000Km. Cambelt changed about 1000km ago

Thanks for the suggestion however I got the same fault code with the old plugs and the misfire is infrequent and a small proportion of driving time (<5%) of driving time that I probably wouldn't detect any difference! Think I might have to bite the financial bullet and get the full diagnosis
