Thanks folks!! The search is on!!

As I expected the lights came back on. I'm thinking it may be the MAF again. I had a problem it a year ago and replaced it with one from Auto zone........ after three failed attempts at O'reily's. Should this prove to be the issue again, yes I will get it from Volvo (FCP) on another issue, is it jus...

oxygen sensor, down stream? is new. Odd thing, all is good now. lol Check engine light and all went out this morning. I am going to continue searching for vacuum leaks and maybe just replace all the lines.

She has no mechanical/electrical know how what so ever. She tells me an idiot light comes on about a bu...

I just replaced the serpentine belt a couple months ago. MAF and upstream O2 sensor too. Sure has a familiar ring there!! haha Went through hell with that MAF too. Tried to save a few bucks at O'Reilly auto, gave up after the third bad one. Got lucky at Autozone.

thanks!!

woo hoo!! Parts on order!! I'll ask here but may start a new thread.

When installing the timing belt the tensioner is heat sensitive? Pretty sure I'll be a good 4 or 5 hours into the job when I get there? Would that be long enough to be "cold"?
