2002 F150 V8 Running problems
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!
