| Did the stealership scan for or did they try to pull codes? Does it do this everything or just when cold/hot? How could they not find anything wrong if it always does it? I would check sensors and vacuum lines... |

| Isn't it still under warranty? I'd try a different dealer.

| I believe the dealership pulled for codes. It usually stalls when hot. Its 5.3L with 19,000 miles. Will have the fuel filter changed but I dont think this may be the problem. |

| checking codes is for autozone. the dealer should be doing a full scan checking the actual sensor readings

| All I know is that the dealership told me that they checked "everything" out and found no problem. I dont have much faith in that dealership. |

| I also noticed that the rpms are lower than 1 when in gear and I have my foot on the brake. Occassionally, the rpms lower a bit and go back to a half to quarter rpm. I dont know if this is normal. |

| rpms should be lower than a 1000 when put in gear. should be close to the 500-600 mark depending on engine and make model year. in park, they will run 700 to 850. maybe a little more depending out ambient and internal temperature. |
