Uneven Idle
Not always, but often enough when I start my 87 F-150 with 302 fuel injected engine after its warmed up, the engine will rev up and slow down over and over until I hold accelerator down enough to race engine steady. Any suggestions to whats causing this would be greatly appreciated. I,m thinking throttle sensor, but thats just a guess.

Mine does the same thing, after its warmed up, it will cycle for a bit and sometimes it will stall. Otherwise it runs fine. Hopefully someone here can help out, as i have just dealt with it for a few years.

This problem was discussed in a couple different threads. It seems to be a popular occurence with our trucks. Here's a thread that may give you some ideas, if I find any others I'll post them. Good luck:
