I was driving down the road the other day and my 87 f150 started sputtering.Changed the plug thinkin that was the issue and its still happening. Today it completely lost power when i step on the gas kinda think its flooded.It broke down right in front of a garage haha but the mechanic thinks its just the regulator,anyone know?

need help

 

need more detail. are you getting spark? are you getting fuel? i guess not if the mechanic thinks its your regulator.

 

I've got the same truck. The only time it sputters is when I'm running out of gas. You have dual tanks, right? Does it happen with either tank? '87s have 3 fuel pumps. One in each tank and one on the frame. If it happens with either it can be the fuel filter or the frame mounted pump. You should do a fuel pressure check. A quick check for the regulator is with the engine running, disconnect the vacuum from it and if idle picks up it is working. This is assuming it's running well enough to idle. When I have any problems I always start by reading the computer first. It usually gives you a place to start looking.

 

im new to this truck and ive read up on it.I do have spark,when i pull the vacum line out of the regulator the idle increases.Ive change plugs.Im stumped her it idels but kinda rough and i lose power when i get on the gas,while it sputters.i really dont know what to do and really dont wanna put it in the shop

 

Idle increasing when vaccuum line is pulled off of regulator is probably normal. Have you done a compression check? Does it have any codes? Is engine temperature normal or is it still cold?

 

Check for computer codes. Detailed description of how in the maintenance section. Check the fuel pressure.
