99 F-150 4.6 miss, hesitation
when i come to an abrubt stop my truck cuts out and if you don't let off of the brake it will sometimes die. also, when i back up and brake to put the truck in D, it will sometimes die. also, when climbing hill it sometimes cuts out. Can anyone help? i changed plugs and wires. also changed fuel filter and cleaned iac valve.
check engine light not coming on.....
when you accelarate, if you don't give it a lot of gas it falls out, as well.

You are having a problem with the IAC [idle air controller]. The IAC can be cleaned but sounds like yours needs to be replaced. Your idle can not be adjusted, the IAC and the PCM controls it.
