| Thanks again. I will take a look at autoweb.com also. Your selection sounds real close to what I would probably order, except I think I will go for the lsd option, too. By the way, how is your mileage? | |

bpeebles - Thanks for the idle info and the hint on cleaning up my "multiple posts". Just reinstalled IE-5 and it looks like that cleaned up my problems but will see when I make this post. The only time the Quad stalls is because of me being too fast off of the clutch on starts. Family has four vehicles some with autos so sometimes one forgets. I'll start using your "Accelerated Engine Teaching Process" today. tmiller - Your dealer sounds like my dealer - Dodge (Five Star) first then expanded with Chevy. Also will provide free towing, within 15 miles of dealer, if their advertisement plates are on front and back. Again, I said "no" to all of that. On free oil changes, they will use synthetics if you provide. Someone ought to get shot for needing that oil filter "trap door". |

Re post 494 my mileage for the last tank pure city diving, all stop and start, was around 12.2. I am getting around 15 for mixed driving, town 60% freeway 40%. I took a trip to Reno a couple of weeks ago and between SF Bay Area and Sacto (all freeway) I was averaging 17.5. Going through the Sierras I dropped down to around 16 because I had a heavy foot through the mountains. Coming back my gas mileage really improved, sometimes 99 MPG coasting down the mountains. :>) I am not keeping a running record so the above MPG are estimates based on my memory but I have been know to have senior moments. I don't think I mentioned above but I also have 3.92 rear end. I have not put on a KN air filter yet but may do. Others seem to feel it makes a difference. So far very happy. I had a couple of small problems which the dealer took care of right away. Excellent truck and this forum is extremely helpful to all who come here. Good luck Carl |

ozark - I have visited Landers site several times and wish they put some details on what each truck had available at their price so I could do some comparisons. carls5 - I had to make a flapper valve run tho the local Lowe's store today and parked next to a red QC Sport 4.7 auto with all the goodies and with a matching tonneau. Great looking vehicle! Anyway, after making my purchase, I decided to wait for a while to talk to the owner. He raved about it, couldn't say enough about how happy he is with it. He's getting about 15.5+ mpg now, started out 12-13mpg; the overhaed console computer a bit lower than his own calculations when he fills up. I am really beginning to work my wife, too. Also took my 4 year old grandson out last Sunday to look at some on the dealer's lot. Got him excited about a new truck, too. Can't hurt to have all the allies you can get! |

My 2000 Dakota 4.7V8 used to exhibit a 'hunting' idle for up to 6000 miles. My symptoms were ALWAYS seen when the road-speed was above 0.0 MPH. (As soon as I came to a complete stop, the idle would 'lock in' at the proper setting.) I brought this up to the dealer several times and each time they reported that the idle speed was correct. (The boneheads ignored the problem.) I have the DODGE shop manual and have read thru it several times. The on-board computer has a 'fuzzy logic' algorithm that allows it to 'learn' certain settings (IdleSpeed, Ignitiontiming, InjectionPulsewith...etc) These settings are stored in memory based on a SIMILAR CONDITIONS WINDOW. (AirTemp, Humidity, BatteryTemp, ExhaustTemp, AidDensity, RoadSpeed ...etc) These are stored in both short-term and Long-term memory and included in the algorithm for learning. Given this knowledge, I realized that the onboard computer needed time to 'adjust' to different conditions and 'learn' the best way to idle under these conditions. I found that I could speed up the learning process by allowing the computer time enough to figure out how to idle. I began to hold the clutch in on long down-hills coasting along between 35-50 MPH. At first, the idle would 'hunt' for over 40 seconds before beginning to settle into a constant speed. After several 'teachings' over the course of a week, The idle began to 'learn' faster and settle into a solid speed much faster when I held the clutch in. The occurrence of stalling was reduced too. Now, I have about 9000 miles on my Dakota and just for fun I held the clutch in for several minutes down a long hill yesterday...NO HUNTING AT ALL. I attrubute this to the onboard computer having learned how to idle under those conditions. (The long-term SIMILAR CONDITIONS WINDOW has some real data in it now) Do not get me wrong... I still experience an occasional stall but this is usually during slow manovers. (Such as backing up a short hill) Rarly, after such a manover, When I push the clutch in, the idle drops to almost nothing and somtimes the engine stalls. I hope this information is what you were looking for. Does any of this sound simular to your experience with your Dakota? |

Just to add to bpeebles - 'problems' with the computer not really knowing how to react are really connected to situations that the truck hasn't experienced very much. Initially this is everything of course, but the truck soon gets used to common events. By making uncommon events more common we can help the truck to learn how to behave - that is why bpeebles clutch down coasting works well. I had a problem with warm reversing, but solved it by reversing into the garage at the end of the day for a while rather than reversing out in the morning. Incidentally, much has been made of the polite and friendly attitude of the Dakota topics, but I saw a trend a few posts back that I think we should continue - b peebles was referred to as Mr. Peebles. I think in future you may call me Mr. Jordan, Sir, God - well you get the idea  Have a pleasant break for memorial day my friends, and regards to all my fellow veterans and current servicemen. |
