So last time my Volvo 2.0L turbo was having misfire problems, I changed the spark plugs with some Denso Platinums and the problem went away and the car drove great - for about a week. It has been running like crap for a while now and today I changed the plugs again. This time I went with cheapo Autolite Iridiums. Again the car runs and drives like new, but for how long? I really don't wanna be changing the plugs every week. Two of the plugs I pulled looked fouled and the other two looked good. What would cause the plugs to foul so quickly?

Are they fouled from oil? like wet or dry fouled?

Wet, seems like with fuel.

How is the plug gap?

Are you sure you're putting turbo specific plugs in?

Anything can cause plugs to foul. Too strong a spark, weak spark, oil contamination, excess fuel, too cold a plug heat range, etc.

How many miles on this pig?

Fuel filter replaced ever?

I suspect maybe it's time to have the injectors cleaned. Doctor Injector does a great job and they are very reasonably priced.

The car is fouling plugs because it is running in limp home mode.

That's what that light means on the dash.

I told you this two years ago when I last worked that car. Razz

Hell if I know. Last time I messed with this car was two years ago. Had SES light on, smelled and felt like it was running rich, and John was complaining of fouled plugs and poor economy.

I told him this was a no-brainer and he needed to pull codes and figure it out. Then, because John Stahlman, nothing happened for a very long time and now here we are. Razz

That's all John sees.

Rock on!

The code was for a mis-fire if I remember correctly.

What kind of dead?

aaron_sK · Posted: Thu Mar 28, 2013 8:48 pm Post subject:

From his text, the oil light came on, he pulled over, checked the oil and it was full, so he continued on his way and the car started smoking and died. This happened in the middle of the 520 bridge.

Maybe the oil pump went bad?

Nothing like breaking down in the middle of the 520 bridge during rush hour! Very Happy

520 sucks

Guess you found the source of fouling.

Sucks, but we all know the Swedish/Danish girls when mistreated by their fathers become self destructive.
