The rattling sound comes somewhere under the hood, low compression, very rough idling and slight vibration at take off. It's like the sound you hear when you select a high gear for a slow moving car. I've replaced the engine of the car yet, the problem persists. The truth is that I have no mechanic that knows how to do solve my problem.

By choking emission I mean, the smoke from the tail pipe has the choking smell of burning metals.

I think the catalytic converters are bad. Is there anything wrong if I change them with those of Japanese cars? They are very expensive in this part of the globe.

If you're not subjected to emission laws won't hurt to try-To confirm the Cats-disconnect the exhaust pipe on the exhaust manifold or a pressure gauge
