Car is currently running on 2 cylinders. MAF sensor, coils, injectors, fuel pressure all check out ok. Also, after looking at it over 2 hours it wasn't always the same 2 cylinders that were firing. No codes are being shown currently. Seems odd that it would not have a misfire code.

A test light was attached to each injector plug. Each was tested individually and only 2 were receiving a pulsating charge. The other 3 received nothing. Therefore I assume PCM was not energizing all the injectors. Sounds like a bad PCM but I wanted to see if anyone had any other ideas. Thanks.

 

Bad PCM or possibly connector. -Steve

 

It was the throttle body. Apparently its a common problem. Volvo has extended the warranty on this part to 10 years and 200,000 miles so I took it to the dealer for the fix.

 

What year and engine is your S60?

 

2002 2.4 liter (not a turbo)

 

What year models are affected on that TB recall?

 

I believe it pertains to 1999 thru 2002 on certain models. Also, from what I've seen it only applies to North America but you should should check that fact. I called Volvo to confirm that I qualified for the extended warranty before I took it to the dealer. The Volvo customer service folks were able to validate it quickly using my vehicles VIN#.
This website has some info on the subject.
