Hi Update.

Ruled out MAF sensor see previous post.

I disconnected the battery for several hours to reset the ECU. (no previous check engine light). Started the car and it ran and drove great for about 30 minutes. I even turned it off to get gas and it fired back up and drove home. Parked at home for 10 minutes then tried to fire it up and it stalls.

This rules out vacuum leak since it drove normal after an ECU reset for 30+ minutes of driving.

More facts! When I was driving after the ECU rest, I did several full throttle accelerations with no issue. Only after about 25 minutes of driving did I sense bucking and hesitation as I "rolled" into the throttle.

Maybe its the Throttle Position Sensor after it gets heat soaked?!

Thanks
