Was anyone else with similar problems running a cold air intake?

Oh, I thought maybe it was from getting so much salty air in from the open cone

I have 4.0 and gotten the same thing. Smelled like burning plastic/coolant to me. When my dad was checking it out, we discovered I have a weeping freeze plug at the front of the motor. Hoping that is the problem.

Interesting. I'll take a peak at that! That could explain why it *appears* I'm slowly losing coolant (though I haven't check the current level vs the mark I made a couple weeks ago).

Mines been slowly disappearing too, so we weren't exactly sure where it was going. I believe its the first freeze plug on mine, it was difficult to see/get a flashlight in between the manifold tubes and block.

Hahaha! Yup! Between the wife, baby, J-10, TJ, WJ, two jobs, and family vehicle maintenance, I barely even have time for the mistress!

Just a thought, I had a Tahoe that had a bad rear axle seal and it caused gear oil from the axle to leak onto the brake rotor. When I drove it it caused the gear oil to burn and burning gear oil smells more like garbage than any automotive fluid I can think of.

If it comes back maybe check your rear axle seals or for gear oil leaks anywhere, really.

Saturday, I noticed my radiator fan relay(s) are shot. In 04, they're located in the fuse box under the hood. I wonder if the smell was the relay(s) toasting themselves...

Add me to the coolant leak camp.
I'm thinking there's a leak that's only apparent when the system is pressurized. Small for now but could get big in a hurry. Can you do a radiator pressure test?
Sometimes a parts store will loan the equipment and it's no more complicated than clamping on a hand pump with a dial gauge to the radiator fill neck to see if it can hold air pressure for a given period of time.

Next time I stop by O'Reillys, I'll see what they have on hand. If they have the proper tool, they'll probably let me borrow it for a bit. They know me too well...

Got my freeze plugs fixed last week and haven't smelled it since. (It got pretty bad near the tail end, was smelling the burning coolant for 10-15 minutes straight sometimes.)
