Ok so I was right. What should I do after the reset? Idle through three fan cycles and then drive it hard?

 

Drive it normal... it will learn

 

the ECU reset will not fix your issue, since you asked I posted.

your map sensor sounds like the culprit

 

Don't just "whack" the MAP. Actually take it off and make sure there's no dirt around where the plug goes or where the sensor itself sits. I hit the thing a few times to no avail. . .simply taking it off and putting it back on solved my problems. Hopefully it'll help you out.

 

I did the map whack on its own without the ecu reset and it made it a little better. The hesitation was shorter and less noticeable. I did the whack again after I got home, but haven't drove the car yet to see if it made the problem go away completely. Hopefully it did, I will see tonight or tomorrow morning when I drive it again.

 

It turns out it was the oil. For some mysterious reason it was VERY low on oil. Next time I go somewhere to get a oil change I will have to double check how much they put in my car because I think the last place didn't put enough. I added two quarts and it is now in between the low and high point a little closer to low, just to give you an idea of how low it was. Thank god I didn't drive the car much while it was low.
