What is the cause of Choking Emission
Asked by Dumo JackAnswer
Where is the noise coming from?
Choking emission?????????????? explain in details-don't quite understand it
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.
Check the exhaust system for restiction
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
Thank you for your patience and untiring effort to render valuable advice to help me.
