Customer Question
Pulled up codes 0344...

Pulled up codes 0344 and 0340. I changed the cam position sensor near the eng air filter already. Still comes back.

Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered?

Cam position sensor.

Mechanic's Assistant: What is the model/year of your Dodge?

0300 for that I changed the ignition coil pack, and the 0340 and 3044 codes.

Mechanic's Assistant: What year is your Dodge?

At home just got in from work. Noticing jerky acceleration now since a week ago.

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

The last thing i did was to change the ignition coil Spark plugs and wires. Also changed the radiator and still i can't tell where my coolant is going.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Transmission levels ok dont know why it gets jerky at acceleration and just got those codes 10min ago from AutoZone 0340 0344

Ok, it sounds like you may still have a small misfire happening when you step on it. This would explain the jerky acceleration. If the mechanical timing is off it could also cause the codes you do have and the misfires.

I think I would run a compression test to see if the timing is off. If you have a scan tool that can see the timing that would be a lot easier for you. You could also check the cam sensor via the code or scan tool.

It sounds like the timing chain may be stretched and causing the cam code to appear.
