When you changed the plugs did you look at them to see any thing different about 3 and 5 plug, they are next to each other at back engine. ? Could be a leak and it burns off. ?Could pull plug on coil and turn engine over than pull plug to see if damp. ??

?My 2002 EVC runs rough on startup but runs great after a minute or two.? I have a check engine light and the following fault codes:
- 16524-Oxygen (Lambda)Sensor B1 S2 P0140b -35 - 00 - No Activity
- 16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35 - 10? - Intermittent
- 16689 - Cylinder 5? P0305 - 35 - 10 - Misfire Detected - Intermittent
- 16687 - Cylinder 3? P0303 - 35 - 10 - Misfire Detected - Intermittent
Because it runs fine after several minutes many of the obvious causes do not seem to be the problem.? I changed the spark plugs but the problem still exists.? I would appreciate any input about a possible cause.
Thanks,
