In the 5 months I've owned my 90 cherokee, the idle on it has gotten signifigantly worse. I've replaced the O2 sensor. That doesn't help. Whenever I'm in drive and at a stop sign the idle drops signifigantly and sometimes I can hear a rattling noise at the back of the car. Also when the car is in park it has started to idle rough. I look under the Cherokee and see the catalytic converter and muffler both vibrating and kind of shaking. What could the problem be? Do I have a bad cat. converter, if so, if I want to put a new one on, do you bolt it on or weld it? Could be some other sensor?
