    I have the same problem, we have replaced plugs, wire, oxygen sensor, EGR Valve, and once we replaced the wires and plugs it stopped for about 2 weeks and started again. I was told to check out the Catalytic Converter.

There is only 1 cam sensor, if the codes are pulling bank 1 it is your front 02 sensor it will only have a second number if you have a dual exhaust

Had similar problems occur on various Chrysler products manufactured since 1986. What I did was remove the computer from the car and then take a Dremel tool with wire brush attachment and lightly buff all the pins of the computer--tops, sides and backs. After this I then take a jewelers round file and insert the tip into each connector pin hole and very lightly file it to remove any corrision. When I reassembling the connector plug to the computer I placed a good size dab of silicon grease on the plug in the center (acts as a seal when seated). This has eliminated the problem on four different vehicles.

My car wont accelerate and there is a loud popping noise on the passenger side when it tries to go


Dodge stratus V6 ?
You should have a check engine light on in your dash.
You will need to have someone plug in a OBD II reader to retrieve the code.
I believe the loud poping noise you hear is the engine backfiring, from either a fuel or electrical problem.
Please let me know what you find.

1999 Dodge Caravan with a code 23. What does that


OBD-II Trouble Code Technical Description
A P0020-023 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020-023 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn't contain cylinder #1.

Causes
A code P0020-023 may mean that one or more of the following has happened:
  • Faulty oil control valve (OCV)
  • Open or short in the VVT/VCT circuit
  • Open or short in the OCV / solenoid valve
  • Damaged computer (PCM)
Possible Solutions
Some recommended troubleshooting and repair steps are:
  • Carefully inspect the Bank 2 VVT/VCT system circuit wiring and connectors, repair as required
  • With a warm engine, test the operation of the OCV, replace/repair as needed

2004 Dodge Grand Caravan engine light on, missfire


That is a code for the secondary (spark) circuit on cylinder number 3. It is usually caused by a bad connection between the coil and the plug (take the coil off the plug and check for moisture in the boot). If not, it might be a bad coil...

Engine Trouble


Your getting backfires? hmm interesting. Seems like your engine is getting flooded and either purging it out of the exhaust or burning it all at once or both (backfire). Sounds like a leaky engine valve to me.There again the bluish smoke indicates to me thatyou are leaking oil somewhere- bad rings or head gasket maybe, which could cause a loss of compression which could also cause your problems.That rattling from the left/rear side sounds like a bad muffler try kicking the muffler (not hard though) next time you walk by it.

Hesitation at 40mph and 50 mph.


A pop and hesitation is likely a backfire. The hesitation around 40 and 50 would be in keeping with that theory. There are several reasons you might be getting backfires and hesitation. If your ECM is adjusting the engine to run too rich this could happen. Misfiring might be occuring. Timing could be out. But one of the most likely is a restricted exhaust, likely due to a plugged, damaged or worn out catalytic converter. In some cases the converter may be bad enough to be giving you some performance problems, but not yet quite bad enough to signal an error. A vacuum test can help confirm whether this is exhaust related.
