throttle help
yes i have a 1987 f-150 4.9 straight 6, efi. sometimes when i am driving it the throttle will just surge up real hard. and sometimes darn near die on me. and others it will just run fine. i have replaced the throttle air control valve and it still does this. i have found a valcuum line that is all dry rotted but not sure if that would be causing the problem. i have been told to replace that and or the throttle position sensor. tight on money so wondering what will be my best bet.
