Thanks. Looks like it was the MAF. I cleaned it previously but I didn't realize I was only getting what I think is a temperature bulb, not the diodes deep in the assembly. It seems like power and gas mileage is coming back. Does it make sense to pull the battery to reset the computer? Thanks again.

Hi,I have a 2004 Base with 137k miles. It has been about trouble free. I changed a belt tensioner at 50k miles and an 02 sensor maybe about 5k miles ago, but thats about it other than routine maintenance (plugs, tranny fluid and oil).

I cannot smell it with the window ...

It only seems to, or mostly happens, around 35-45 mph (so 4th gear). It's automatic. I take my foot off the gas, the RPMs drop, to lets say 1600 or so...
