MUST REV for 5-10 minutes after jumping dead battery by: Anonymous
Like my 2000 Dodge Dakota, if you have to jumpstart a dead battery -- assuming the alternator, voltage regulator, etc. are OK -- you then HAVE to WAIT five to ten minutes, holding the gas pedal down (or feathering it) before the computer gets back to normal. Another way of looking at it is you have to rev the engine for a little while while the alternator charges the battery up sufficiently for the vehicle to idle on its own. Of course if you have the time the best thing to do is just charge the battery up with a slow, plug-in battery charger. But if you have to jumpstart it be prepared to hold the accelerator down a bit and keep revving it -- 1000 to 3000 RPMS should do fine -- until it idles on its own. Though annoying, this appears to be normal.

I had the same problem... by: Anonymous
Have you checked your battery? I had the same problem. I installed a new battery and the problem went away.

I had the same problem and this is how I fixed it. by: deney
I had the same problem with my 2003 dodge ram and i brought it to the dealer and they told me my computer was shot and it was going to be $6000 for a new one. so what i did was got it running and had to keep it at 2500RPM to stay running then i noticed my engine temp gauage was at the max and it got thinking about it and what i ended up doing was changing the engine tempsensor and now the truck starts up and idles the way it is suppose too. What happens when the ENG temp sensor is done it tells the computer to cut your fuel so the engine starts to shut off therefore you have to have the RPM's up just to keep it running, so in the end it cost me $58 bucks for the sensor and 25 bucks for a chilton manual and it's fixed thats alot better than $6000 for a computer give it a try i'll bet yours will work after you change the temp sensor out.
