I'll check the fuel filter, but what was that about the main fuel relay?? Is this the common issue I was thinking about?

Also, I did get my O2 sensor replaced recently so it's probably not that. Forgot to mention that it was replaced. My mileage seems about average with my usual so I haven't seen a drop in that...

Oh yeah, would a problem in the fuel filter and/or main fuel relay also cause my #1 problem (low idle)?

Thanks for the feedback guys!
