2002 S80 T6 Blinking Check Engine Light and shaking
20

Asked by Stoltzfus Jan 19, 2013 at 08:51 PM about the 2002 Volvo S80 T6

Question type: Maintenance & Repair

My 2002 S80 T6 has almost 190K miles and the other day when I started it, my idle was low and the engine was shaking.  I was only a couple blocks from home so I decided to get it there.  When accelerating from a stop the car shakes bad and at aroung 1500 rpm the solid check engine light starts to blink.  I think this is a misfire but not sure how to diagnose.  I took the coils out and tested them for continuity and they all test the same.  All of the plugs are white so it is burning a little lean.  Any ideas?  My power steering pump has also started leaking and some ps fluid leaked down into my alternator.  Could this be causing the computer to create the misfire?  Don't know the codes yet but will be getting a tester soon and should have them in a couple days.

The codes will tell the tale. A flashing CEL is very bad, the engine goes into limp mode and the car should not be driven very far. In limp mode power is reduced, the fuel mixture is enriched, cooling fans are forced on and sometimes RPM's are limited.

Ok, I got a scanner and got the code: p0300 - random misfire detected. Could this be a faulty Mass Airflow Sensor? All of my plugs were white suggesting it is running lean. How would I test the MAF sensor. Can I bench test it with a multi meter?
