Why does my ford escort van 1.4 efi rattle from the catalitic convertor


It is possibly that the cat converter has failed and the bits are rattling around in the case. It may be that the noise from the rear end of the cat is the broken bits trying to get out the exhaust pipe and blocking the system

It could be a loose heat shield on the exhaust. How ever I have seen the inspection plate loosen at the torque convertor housing. There may even be a loose bolt on the flywheel.

REPLACE BANK 2 o2 SENSORS 1996 CONTINENTAL


bank 1 and bank 2 refer to the positioning of the sensor on the car, bank 2 just means the second one, so if you start out at your exhaust manifold and inspect the piping going back, the second O2 senor you find will be the one you need to change, it will likely be around or near the catalitic convertor.

94 Bravada that stumbles and stalls.. won't start when warm..


Try checking the exhaust flow when someone else is pushing down on the gas petal.The farther the petal gos down,the more exhaust should be coming out. I replaced my catalitic convertor at 44000 miles, it was clogged. I had them install a high flow type.

This sounds as if you have a damaged catalitic convertor have it checked by your local exhaust centre.

Gas milege falling and loud squeal and rattle


Most likely your honeycomb is broken loose inside your catalytic converter.If it breaks into smaller pieces it can start to restrict the exhaust outout & make starnge sounds like a turbo winding up.I would replace the convereter & go from there.Hope this helps
