vauxhall zafira engine problem


hi all my 2003 zafira 1.8 petrol has now got the engine fault light on ( orange engine one without the spanner) it starts fine but when cold shudders coughs and splutters for a while before getting going. I checked the airfilter and the light went out even though i didnt actually change itbut after a week it came back on. I then changed the filter and again it went out for a week but eventually came back on. It was still spluttering when very cold but not quite as bad. I have now tried changing the plugs but it doesnt seam to have made any difference. It does seam to be a little down on power but cant be sure as i dont usually drive it. dont know weather the fuel consumption has changed either. Any ideas what it could be please. thanx, Dave

forgot to add plugs looked ok when they came out nice tan colour.

is it possibly the egr valve or gunked up throttle bodies. from what ive read though this seams to be 1.6 8v's

Coil packs are a very common fault also , but unless you get a diagnostic scan and see what faults are shown just guessing .

have read about suspect coil packs but would have expected a plug to be fouled if this was the caase. have just found out about pedal trick to read codes so ill post them on hear if anybody can decifer them

latest update i have read codes using brake and accelerator method and got the following codes 0170 and 0335 any ideas on causes and fixes????
