need help
i have a 2000 dakota slt, ext cab, 3.9, auto, no mods. put in a new jasper 3.9 motor kit in it. everything new except for the intake and everything on it. occasionally it will get a bad skip in it with a spark knock, then almost shut off completely, if the ac is on it will knock off. always starts back with no problem, then it may not skip for a month, or in 20 minutes. it sometimes will go for a month and not do it. it shows a misfire in the odd cylinders only. also the a/c compressor will shut off at times and not come back on for 30 minutes, then sometimes it works perfect. any help would be appreciated.
