First day - engine light and 4 cylinders

[Jsethen]

I just pulled out my "new to me" 2008 vert. I was driving home this evening and all of a sudden the engine light came on and it seemed to be runing on 4 cylinders. I drove straight to the the dodge dealer so they could look at it in the am and figured I would try turning it off and restarting. Fired right up and ran fine. Any ideas? I was thinking maybe moisture in tank from storing over winter with less than full tank. It only has 3500km on it.

any codes stored in the pcm?
where are you located? sounds europe or canada with the "km"?

Mods of any kind?

Ethanol fuel blended gas?

Doesn't store well in your tank past 90 days.....

Hopefully, Jsethen can extract the codes either by the key method or with a CAN bus capable OBD II reader since there are multiple potential causes.

no mods, not sure what fuel was in when stored. need to find key code extract method on here again. saw it once but forgot exactly how it said.

Try this old post from Mark:

The key will start out in the "on" position, you need to turn to off, on, off, on in about 2.9 seconds. To fast and nothing to slow and nothing so it may take a few times to get it right. When it is done correctly there will be codes (some) listed in the odometer area. If there are no codes there will be a row of dashes and then say done.

Hope this helps."

Sounds like some code and resulting "limp mode".

Just curious, how's the battery?
