Van has no power it feels like a restricted exhaust to me. I took a compression test with good results pretty even 1st puff 75psi and 5-6 puff 180. did a running compression test with even results on the cylinders 75psi running and about 115psi snap throttle. I did remove both oxygen sensors and drove but still no power any suggestions?
Hook up a scanner and run the engine. Put the scanner in data mode and look at throttle position, manifold pressure, fuel pressure, etc.

Sounds like it needs spark plugs and wires, and a fuel system treatment.

First, keep in mind that as you begin to remove these doors you run the risk of causing serious scratches to the paint and glass, so put some masking tape and/or plastic sheeting around both sides of the door (rear quarter panel and rear glass, front door and front door glass)
I would get a Haynes repair guide since that's what I have to work from and it will tell you step by step with pictures, what to do. It's not hard, but you need to get all of the attach points unhooked to be successful. Suggest you have a helper working with you to keep the door steady.

do this calibration reset, it will usually rest he lights and the ac will work again, if it doesn't reset you have a part failure and the dealer you need to hook a Chrysler scan tool to diagnose the problem.
CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:
Set Blower motor ON HIGH
Set Mode position to Panel
Set Temperature to Cold (Both slide pots if equipped)
Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)
RESULTS:
All LED's will turn on for 5 Seconds
Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing.
Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.
After all tests have passed, Calibration Diagnostics and Cooldown can be run separately

Hi there good luck with it ,,,, this is what I did. It was going to take a week to order one from Schucks auto so I took matters into my own hand. I removed the valve from the car lots of posts on how to do this I then pried up the three double tabs with a screw driver marked the cap location to the body and carefully removed the top plastic cap. inside you will find two spade lug style connectors and the top of the plunger. this is a solenoid style egr. If you can push down on the solenoid and it returns easily great. the inside of the cap has a small plunger that is the sensor part. the solenoid should read about 7 to 8 ohms resistance at the spade lugs. the sensor should read around 3 thousand ohms and one of the terminals should vary between 3 thousand and 0 ish. If thats all good the problem you may have had is the electrical connection between the spade lug connectors and the two leads that point straight down from the black plastic cap. Give the spade lug connector a gentle squeeze with a pair of pliers and use a bit of electrical grease and carefully press the cap back down into position with the pins inserted into spade lug slots. reinstall and celebrate.

The o2 sensors are located on the exhaust system.The upstream in on the rear exhaust manifold and the down stream is in front of the catalytic converter.Usually when they are bad they will make the check engine like go on.Make sure the air filter is clean,tires at correct inflation,alignment is to specs.If the vehicles pulls to one side or the other or steering wheel is not straight when driving down a straight stretch of road.Also tires are wearing normal.Use cruise control where ever on highway.If you let your vehicle warm up in winter.This also uses gas.Hope this helps.Good luck.

Check that the emergency brake is fully DISengaged. I had that problem with my 2004 so cabling had to be adjusted. Also check that your tires are aligned properly. This can create a LOT of resistance. What are your rpms as compared to travelling speed? What kind of gas mileage are you getting?
