My Mrs. picked me up from the airport the other night in the Statesman after a month in Baghdad and straight away I noticed that the car was louder than usual. It also has a nasty rattle/vibration underneath at low speeds while under load (e.g turning into a car parking space) and the other night she said while she was sitting in the car park after work talking to someone (idling while stopped in gear) the car almost conked out.
Any ideas?
Possibly the substrate in a cat has dislodged and is shifting round in there. That's not uncommon.
this happened to me. thank god it was only that i thought it was something much worse!
Happened to my mate except was that bad that the engine wouldnt run above 1500rpm he thought engine was shagged I said nah man definatly a fuel issue or your cat is f***ed and turned out to be his cat.
You could just smash the centre out yourself you know?? just till ya get newwies
When idling does it make any unusual noises from that area (outside the car)?
Depending if its melted or the insulating blanket is gone....
But I would say catalytic converter from what you have told us.
