Chi_S_Four

I've got a 2000 tip S4 with 97,000 miles. Only 5,000 are mine. After dinner last night, the car began running rough in city traffic. After I had only driven 10 minutes, maybe 2 miles, smoke started coming from under the hood.

I stopped and doused the back of the engine compartment with water, let it sit for an hour then had it towed to a shop.
They just told me I had a missing heat shield near the drivers side cat, and that I caught some insulation on fire near the fire wall. What would cause such heat on one side near the O2 sensor?

Now I have a CEL and the car is running really rough. I don't want to drive it 20 miles to a shop I trust in the Chicago suburbs, but I haven't got any better ideas.

Any suggestions, advice, or speculation?

particularly off-throttle?

If so, your turbos may have left the building...

have it towed to the shop you trust

Sounds like you may have melted an O2 wire what does the code say? Any pepboys or autozone will read it for free. Cats definitely get hot enough to melt anything close to them.
