Fuel mileage loss, fix = clean the Map Sensor again.

I probably should check ours at some point.

But we may also be in "the dip" that everyone seems to have around 130k miles...

For 26 bucks new it's a 10 minute swap.

Drove about a 100 miles today combo of highway and mostly stop and go and the mileage has come up about 7 mpg. From 33-34 to 40.3.

Well, that may be worth it then, especially at under $30 and minimal effort, just to see. Ours has definitely been down a little on fuel economy, at least from what I can tell. Our trip up North usually has a good tank (though we did spend most of the week with a ton of snow, quite cold and a lot of remote starting, so that's never good for it - but the drive there or back certainly is), but it really didn't this year.

But I do know people have the "dip" I mentioned, as well, and it seems to go away and the car reverts back to what it used to do.

New sensor came in today. Pretty quick swap, not sure how bad it was compared to everyone elses. I’ve never changed it before. So it had 230k

Looks way different from mone above. Mine was like dry caked on soot. Yours looks like tar.

Where's the old oring?

It’s on there just really dried out and dirty.
Not sure why it looks so different, could it be the delete for some reason?

Could be from the delete.

When my car first started after replacing the map it immediately did a brief adjustment of fuel I am assuming based on the new map data.

It was a sort of stumble for like one second upon immediately starting.

I am definitely glad I changed it. Could have cleaned it but for the price of a new one, hardly worth the effort.

Sweet, just ordered one for ours. $20 from Amazon for the Delco part with the proper 8-digit, cheap insurance.
