lol. No thanks nate.

I notice my gas mileage is pretty craptacular. I foolishly thought in my head I would get similar mileage as my old 94 Beretta 3100 cuz its basically the same engine. Alero is 400 pounds heavier... I didn't think it would be that different. But I guess so. Especially after reading various threads on here where people say they get under 300 miles a tank. Beretta was getting me 400-415 consistently.

I am going to clean the MAF sensor and see what that does for me. 228k miles on her... I wonder when it was done last. I couldn't imagine it would run as decent as it does if that was never cleaned or replaced... would it?

I don't have any idle issues. Sometimes I have to crank it 2 or 3 times in the morning to get it started and periodically merging onto the freeway the rpms surge back and forth very little..(cant notice unless you look at the gauge) between 50 and then its fine after like 55.

Possible symptoms of the EGR or MAF?

Upstream O2 is new.
