Unknown Part

What part is this? My truck is running missing and smelling like fuel. I looked under the hood in the dark and this part is arcing. I assume it is some kind of coil pack, but not sure. It goes straight to the distributor cap.

The arc is where the blue paint is.

That Part is your Ignition Coil

That Part is your Ignition Coil

If I can see orange arcing at night does this mean it needs to be replaced or is it my distibutor cap & rotor.

That depends on where it's arcing, If it's arcing near the wire going in it, then you need a coil wire. However, if it arc's from the coil itself, it may be cracked and will need to be replaced... Let us know how you make out with it.

It is arcing from the coil itself. I removed the wire and it is white and discolored. Cap[ and Rotor were changed about three months ago.

Then replace the ignition coil, it's bad

Thanks, I will pick one up at lunch.

Please let us know if it fixes it, I have one that is burnde white and think maybe mine is bad also. My symtom is intermittent miss at light load.

I'll report back tonight. I just replaced the fuel filter, CPI, & Nut Kit.

I replaced the ignition coil which corrected the orange arc, but it was still running rough. I changed the map sensor and all plugs & wires today. Now it runs like a new truck except a vaccuum leak I haven't tracked down yet.

A/C switches to defrost at high rpm's. After shifting and back to normal rpm range A/C works fine. When on Maximum A/C 85% of air blows on dash no matter what rpm.
