...drive, idle surges and fades? Ford F 150 XL 5.0 L has 171K , Starts and drives but when stepping on the gas while on drive it hesitates and seems to die down..(loses power)..if put on neutral..and step on gas it reacts normal..However it sometimes gets out of this mode and drives better whenever there is no stops ...Idle is somewhat abnormal which sometimes surge and fades especially when it starts before it warms up!...any hint where to look..it's my only truck and I need to make it to work!
Thanks for all replies in advance!
