Okay, i get this noise under my car like a metal pan is rattling or vibrating as if it is loose when im driving and the rpm is at around 2200. Its hard to reproduce the noise in neutral and if you listen closely you can still hear it at idle, but not as loud or vibrating. Does anyone know what this noise is and how to fix it?

I have the same problem on my 93 lx. Can't quite locate it though.

Try checking you motor mounts.

I have the same problem

Me too!

I have the same problem with my car, but I think it's a bit deeper than that. It's real gutless (more than usual) up to 3,200 rpm then it starts pulling. I don't know about you guys, but my 2 3.8L cars always had mostly low end torque and the power seemed to fizzle out at higher rpm's. I can barely chirp my tires anymore from a stop, when before I actually had traction problems. My high end is right where it should be though and I get nice 2nd gear chirps as long as I don't have much weight in the car. I've replaced a big list of parts including plugs, wires, distributor cap & rotor, fuel filter, switched the MAF from my '91, changed the air filter twice, tried injector cleaners, checked for exhaust leaks, and can't seem to find anything unusual. Could this be from my exhaust manifold bolts being loose or anything? Or should I just bring it to a Ford dealer and have them plug it in? It might be easier for me to check the codes myself though. The check engine light used to come on alot too, but since I got dual exhaust that has stopped. Anyone know what could be wrong?

there are Heat sheilds on the Catilatic converters that get loose over time and start rattling and different RPM's

How far along are you on the Mileage record, My supercoupe has 192,000 miles on it with original headgaskets, but the tranny's been rebuilt, I see you are also about a 2 hour drive from my place! (Eveleth Minnesota)

183,000 on my '93 oh and by the way I'm catless! I drive 40,000+ miles a year, so I'm wondering how much longer she'll last. But I'm really anxious to get a '95 4.6L XR-7 and start dumping money into that!

The end all be-all answer....

I posted this in Alex's exhaust question, so you might have already read this.

That annoying hum is the exhaust resonating. there is a TSB on how to elimate it.
