Question about 2004 Chrysler Pacifica

1 Answer

Drove car out of neighborhood. Car hesitated then

Drove car out of neighborhood. Car hesitated then began running rough as though it was choking for power. Got to my office and there was a smell as though plastic were melting. Drove home; same missing-ill performance issue and then went back to tailpipe (muffler comes to edge of bumper in this car) and noticed that the mufler was EXTREMELY hot -- like on fire hot.
This problem came on suddenly --ie, no buildup over time. I''ve done the normal things like check the oil, fluids, etc. and no problems there.

I was thinking maybe and oxygen sensor that went south? A catalytic convertoer that has ceased working? Not sure but boy howdy, I'm not interested in this thing quitting on me in east BF...any thoughts?

Catalytic converter is cloged

Testimonial: "I'm thinking you may be right....i probably need to loosen the exhaust pipe bteween the converter and engine to see if that makes a difference....if so then it's most likely the converter, would you agree?"

It sounds like some thing you have done if the fault started after the tune , did you check the gap on the new plugs, check the firing order as it may be messed up . 4 cylinder 1342 6 cylinder 153624 in direction of rotation.

Replacing the fuse the first time was the right move, becuase it could have been a fluke that it blew. Replacing it again and again was not! You should have found out EVERYTHING that the #2 fuse controlled and verified that the components weren't pulling excessive amperage (shorted condition). By replacing the fuse over and over, you might have made the problem worse by subjecting good components to something that was shorted.

BTW next time pick the oldest guy at autozone to help you, if the counter help knew their stuff they would have told you the same thing I just did!

You need to replace the water pump. It is involved so the easy way is to go to you local library and make copies of the pictures from the repair book. Be sure to take down the vin # and ask your local dealer about recalls.

The most common problem is a partially clogged injector. They should be cleaned about once a year. Also the coil housing is known for shorting out between cylinders on your engine. The reason that its worse with the AC on is because the AC compressor is adding a load to the engine. You should probably take it to the shop and have it diagnosed soon before the misfire damages the catalytic converter.
