Hi guys, I have an 03 with 52000 km on it. Last week the cel came on and was diagnosed cylinders 2, 3, 4 misfire. Replaced spark plugs and ran fine for a few days.
But this morning, after the car sitting for 3 days, when I started it, it runs rough for 3 to 5 sec and after that it runs fine, and the cel came back..........any help would be appreciated?

 

Try changing the ignition coils or the injectors those are some other things people on here do to fix it.

 

What I don't understand is why after the car is started after 5 sec, the engine runs smooth....no misfire.

 

How 'bout that cod3?
