i know it's a firing issue, but i'm not sure where to start.. it runs right while running (other than my vibration i'm still hunting in my other thread https://www.f150forum.com/f10/vibrations-158245/ )

the actual problem is that when i go to stop at a red light, the engine will shut off if the clutch is pushed in or when it's put in neutral. when going down the road, it's fine. no skips, or anything. just when i go to stop.

i believe it's an issue with the injectors but i'm looking for someone who's had the same problem and fixed it. or if someone just knows what they're talking about..

 

So the truck dies when you push in the clutch at a stop light, but not while driving? That is weird... Sounds like an electrical issue with the clutch switch.

 

Sounds more like an idle issue. The computer does see when you push in the clutch to control idle, as long as the clutch switch is working.

 

But its also neutral. And it seems to happen more frequently when i go from a higher speed to a complete stop or just before im completely stopped like rolling at 10 mph.

 

Still an idle issue.

 

What do you suggest i check and how? Im guessing the clutch switch but where is it?

 

On the clutch pedal assembly you will see a 6 pin harness, the PCM feed is the one I'm thinking is the culprit but not sure.

 

And to test it?

 

I would suspect the IAC.

 

And to check?
