do you recomend

many thanks

for a non turbo daily run around basic ngk, denso or bosch be fine .
I would review plug leads too as these when failing can give fishbite misfires  and this damp cold weather ideal for spark tracking .
air filter and maf sensor cleaning be other areas look at .

Plugs and leads via ebay listed below.
Cambaire leads great on the ej201 and 202, fit nice, lengths sensible and have  protective sleeving lengths so if make a little effort they lay out perfect like originals .
They also seem last quite well, haven't found anything better for 2 or 3 times the cost for non turbo models of this vintage .
If you do super high miles and don't like servicing plugs often then better plugs worth considering but these will be fine for non turbo and lower mileage runaround and last well and super reliable . You could spend same money on 1 plug as the set of 4 but for lower mileage non turbo 17 year old run around you be wasting good money best spent else where .

Check you PCV lines for leaks or disconnections, that can lead to a lumpy idle. MAF as above is another one, clogged intake too
