Here is the background. I'm driving a 2003 volvo s60 2.4 turbo. I have a cel coming on saying its running lean. First time it came on it was really cold out. Below 20 dagrees. I dumped some fuel system cleaner in it and reset the cel drove it for three weeks no problem. Yesterday it hit below 20 again and the light came back on same code. And now im knowtacing some power loss. What's this sounds like I'm leaning towards the mass airflow sensor but I'm not sure any opinions?

 

Anyone?

 

I have no answers. But I am impressed at the word "knowtacing". Wow.

 

And that's the reason I moved to a different forum. The lack of desire to actually try and help but rather just make fun of a spelling error. Congrats douch.

 

Asking for help without posting the codes won't get you very far.
