Hi folks
Grooved a 2002 4.7L Dodge Ram 1500 Reg Cab Short Box Sport 4x4 it has 170604 kilometers on it cable driven throttle body, but this baby needs J-B Weld to built up the wall the large bit breaks through at three different locations and routed the idle air passage up the side away from the air flow a little bit of J-B Weld takes care of that, as far as I could see the pcv line is before the throttle body let me know if I'm wrong. Otherwise it was easy to get at and to work on. This guy talks about kms per tank of fuel so it will be a while before I will know the improvements the groove does.
