Missing on heavy accelleration could be something as simple as old spark plugs or ignition leads. Not enough spark to fire the engine under a heavy load.
But reasing the error codes, and probably a visual inspection of the spark plugs will tell you more. If you have never replaced the plugs, it probably needs them done.
Hi this is the engine management system telling you it needs to visit a dealer for a diagnostics check failure is not an opton. using anything other than the correct diagnostic tester results in going down the no hope route as parts get changed that don't need to be.

Since you've been ignoring it for days and weeks, there's really no need to do anything about it at this point.
More likely than not, it will simply die like all of the other 2.7L equipped Intrepids.
BTW it is not worth fixing either. As I understand it, the engine is too small (underpowered) for the weight of the vehicle. Low Blue Book on it is under one thousand dollars -- Good Luck!
The dealer of the car can read the *stored fault and tell you exactly what is causing it. Free code reading by non-mechanics at Auto Zone can NOT pinpoint the cause.
many places will pull codes for a small fee if not for free as long as you by the supplies to fix it there. if you are lucky, it is a loose gas cap.
My check engine light will turn on (not flash) for a period of days to weeks and then will inexplicably turn off and stay off again for days to weeks before coming back on again. I can hear my engine struggle if I accelerate too quickly anymore which sometimes causes the 'check engine' light to turn on again (not flash). I've been to a few mechanics for other problems recently with the car and they've not noticed or made any mention of the 'check engine' light being on.
I drive a 2001 Dodge Intrepid with the 2.7 engine. Thanks!
