5 or 6 cyl?

5-2
6-4

 

We have had the check engine/emissions service needed light on for about 2 years now. Unfortunately we have been through many fixes including the dealership telling us it was the gas cap, to a new O2 sensor, we had the system checked for leaks and they found nothing. It will reset, but then comes on within an hour after we leave the shop. We are suspecting now that it may be part of the throttle body and we are happy that they extended the warranty on the part. We are trying our luck at the dealership again now hoping then will follow through with the "extended warranty". Thankfully your light did go off, but I would not always assume it is the gas cap.

 

I had the emissions system check light come on my S80 also. But, my car was also running very rough. It happened the day after I washed my engine....what was I thinking?
Anyway, somewhere on this forum I saw a post that it might be one or more ignition coils. I changed out my spark plugs, two were wet. Gez, two out of six not firing...no wonder it was running rough. lol I put new coils over those two and viola...that new car ride again : ) Thanks to this forum I saved a bundle...I dont know what a dealer would have charged(scared to imagine) : ) Kragen auto parts wanted about $180 for each ignition coil and a week to get the parts in. So......I ordered it online for $55 each and got them in a few days(original volvo parts too). That Kragen....what are they thinking! lol
