05 Dakota 4.7 Rough Idle
[:@][>:] OK i recently purchased a 2005 dodge dakota brand new. the truck had 90 miles on it when i bought it. after i brought it home i noticed the idle was somewhat rough (aentenna wobbling around 3-4 inchs, and clearly visible when looking at truck body) i figured that i purchased a truck that had been sitting on the lot for over a year more than likely and it just needed to be drive. after putting 1000 miles on the odometer there was no change in the idle. i brouth it to the dealer and they were unable to check the obd2 because the tank was full (newer vehicles must be between 7/8 and 1/8 of a tank to do self-diagnosis). this was friday. i brought it back saturday morning bright and ealy, they told me to leave it and i did. it is now wednesday night and they still have no clue what is wrong with my truck, they have been communicating with chrysler techs and are unable to come to any conclusion. they say they have one the normal self-diagnosing of obd2, have checked all 8 coils, all eight injectors and have monitored output from all sensors and everything seems to be normal, they performed a compression check and that was good (and i knew it would be because the truck runs fine and has plenty of power) so they are now in the process of removing the cams for precision measure?!?!?!?! why?!?!?!?!?[:'(][:@][>:] i dont understand, oh i almost forgot, when i brought it in i told them to look at the harmonic balancer/crankshaft pulley because there is a wobble there, i went to another lot and looked at other 05 4.7s while running and they don't look like mine, i also had a 2000 dakota with the 4.7 and it didnt wobble either, i have explained this to the mech ant the dealer and he refuses to check it or replace it because "that wouldn't cause the problem you are having here" ok im not albert einstein, but i do have an AAP in Automotive technology and i spent most of that time working with obd2, i also work on aircraft drive systems which includes checking and balancing drivshafts, i know what vibration looks like and what it can do to bearings... anyway i know this post is long, i am look for some advice... any input would be appreciated.
