'03 Aviator won't stay on after changing spark plugs

Changed the spark plugs, car started faster than before but promptly died. Second start it barely turned on. From then on it will only start if I'm pressing the gas pedal. I held rpm around 6k, lowered it down to 3, then 1.5. Everything seems fine, let go of gas and dies right away. Just as if the fuel is being cut off.

What could it be?

Engine ran fine before charging plugs but had occasional misfire on cylinder 7 during idle.

Re: '03 Aviator won't stay on after changing spark plugs

Verify your wires are connected in the correct firing order and firmly in place. You'd be surprised how many have sworn that they all ready did, then found out they really didn't. Make sure the clip isn't loose on the end of the plug. By the way, which plugs did you put in?

Re: '03 Aviator won't stay on after changing spark plugs

That's what I was going to check first. Can't mess up the firing order since it's coil on plug and each wire is right next to each pack. 2 out of the 8 connector's clips are broken (one was broken from before and one broke on me while unclipping it) but they seemed to be on securely. I'll recheck all of them, but shouldn't it still say on but idle roughly due to misfire?

I used the OEM Motorcraft Platinum plugs.

Would the grease for the coil plugs cause issues?

I would recheck all connections for vacuum hoses. I can't remember if 04 is still equipped with an Idle Air Control solenoid but it will be located near the throttle body but need to check that also

It was a vacuum hose. That's what I get for trying to rush in the cold dark.

Engines up and running fine.

Thanks guys for your replies.
