2005 Chrysler Pacifica hesitating on acceleration

We just got our 2005 Chrysler Pacifica repaired. The dealership replaced the oxygen sensor to the tune of 250.00... The auto is still hesitating when you accelerate. Any suggestions?

SOURCE: engine rattles at acceleration and hesitates

This sounds like your ignition timing is awry. You'll need a timing light to verify if this is correct. If that's OK the your valve clearances may be a little loose.

A tune up is a good idea.. Also depends when the last tune up was..

I have a 2005 Chrysler pacifica. Today it hesitated and stalled almost 2 miles from home . It would jump to 1000 rpm and stall the rest of the way home?

you should have OBD alarms coming in. It sounds like engine is not getting correct air/ fuel mixture due to failed component or failed sensor. Need OBD code to isolate or work in the correct area.

Driving my 05 Pacifica down the road for 3 miles and the exhaust will turn cherry red and will lose power

Then you ruined the exhaust converters &
oxygen sensors, because you have a timing
problem or rich fuel condition or both

That is going to be a very expensive repair,
once the main issue is found

Hear a clunk a slight hesitation when just starting to accelerate. Repair shop says the motor mounts need to be replaced. Is this something a decently inclinded shade tree mechanic can tackle?

I would say so, Just have to jack up the motor and loosen the mount, lift engine up enough to give you some room. There are two bolts that hold on the mount.

2005 chrysler pacifica code 0420.Changed sensors and catyletic converter.(as recommended by dealership) Lasted long enough to get inspection, light came back on that evening . Been off and on (mostly on)...

Code P0420 is a catalist ineficiency code. It can be caused by a minor exhaust leak. Based on what youve already replaced. Inspect the entire system while its running to find any leaks.

Volvo S60 Hesitation

Had a similar problem recently where I would press the accelerator almost to the floor before I got a response and when I ran the A/C it was worse. Also my car kept stalling out when at idle. Volvo dealerships are extremely expensive. I took mine to a Bosch service center (more of a mom & pop shop) and the price was more reasonable. The drivability (sp?) problem was the rear oxygen sensor for me. I also had a fuel pressure sensor and MAP (labeled as pressure sensor from Volvo) sensor replaced. The parts are expensive, but it fixed my issue. There is a front and rear oxygen sensor so it could be either. The parts are $219 each. The fuel pressure and MAP sensor are cheaper, but only by about $40. They are not hard to replace though. Once I had the rear oxygen sensor replaced the car was back to normal. I have a 2003 S60 with 97K miles.
