Well, I took the battery in for testing, and it was definitely no good. Although, for being the original battery, it did damn good for 7 1/2 years!

The new battery started the Durango right up. It's a little sluggish...but I only drove it 5 miles to work. I guess I'll check the alternator if the battery runs down again.

Thanks for all your help!!!!

 

yea, i wouldnt complain about 7 1/2 years, iv been getting 4 at best out of mine . . .

 

7+ years!


Well you got your money outta that one!

 

It is "a little slugggish" because the PCM is relearning. A reset would have taken care of that an no sluggish from the get go.

Make TRIPLE sure the battery connections are nice and tight.

A reset?Just went through this same nonsense,only I forgot I had seen this before,and bought and installed an alternator first.D'oh!
What's this reset?
Thanks,Bobby.

 

PCM RESET:

Remove the negative (ground/BLACK) battery cable from the post and turn your key in the ignition to START as if you were going to start it up. Hold it there for 20 seconds and remove the key from the ignition. Replace the cable back to the terminal and turn the truck on. Let it sit for a minute (no pressing the throttle) and then turn it off. Once you restate it, you can drive it how you normally do.

 

I like to repeat the key on/key off process three times but that is indeed the correct reset process.

im not sure if this is what indy meant, but i like to cycle the engine on/off 3 times and on the 4th take it for a drive, let the idle settle down then kill it, do that again

 

There is no reason to cycle the engine on and off repeated. That just creates excessive wear on startup when your engine is most vulnerable.

Why are you starting and stopping the engine? It takes anywhere from 10 to 100 starts depending on the process to clear a code assuming the code causing problem is gone. By resetting the PCM, the codes are gone anyways.

I suggest to never start and stop and start and stop and start and stop and start an engine and then go for a drive.

From above, the "key dance" to reset the PCM is often most effective repeated a couple times. Thats all.

i had read somewhere that doing that a couple of times helps to set in the sensor parameters more quickly, if you are doing it on a COLD engine, i would agree that its excessive wear, however i usually do it after the engine is all warmed up before the oil has a chance to drain into the pan.
