Hello all, Just picked up a 97 gp 3800. The car has a rumbling vibration at idle that goes away soon as you give it gas. I believe the mounts are good as it does the same in reverse, drive or park. It also has the Dexsludge problem and it appears the LIM is leaking. It is puddling up in the area between the water pump and the lower aluminum section of the manifold. The car also seems to not have the power it should, and seems to respond slow. It had a code for a misfire in #5, so I changed out the pluggs, they were horribly worn. It's throwing a PO141, the AZ guy told me thats the o2 under the hood, but in researching here it seems that its actually the after cat O2?
Could the LIM leak cause the car to run this way, or is it related to the bad O2 sensor?
I believe this code means the heated section of the sensor is bad. The car runs the same hot or cold. Could this code also indicate a clogged cat?
TIA!
Could be a clogged cat. A vac leak would normally toss the Lean bank code
