The truck runs fine while driving. If you stop at a stop sign or traffic light and leave it in drive it drops RPMs to about 800 and starts to sputter and want to cut off. I have changed the idle sensor and made sure all the lines for air are securely tightened and not leaking. I have also changed the fuel filter. The service engine soon light is on but when I took it to advanced auto for them to read, the only thing that is coming up is that it is running to lean. I hate to have to take it to the dealer and pay $100 to have them read the code. Anyone else had this problem or have any ideas what it might be? I am stumpt!

Just incase anyone else has this problem ever check all the air lines are sealed and the tubes themselves aren't leaking. We took it in and they found the tube that we already checked the connections on was stopped up and cracked. Replaced it for about 30 buck and the truck runs great!!
