Why would Chrysler take the two most bulletproof engines known to man (the 318 truck block and the Jeep 258 six) and replace them with a fragile as glass 4.7 psychadellic SPAGETTI infected, non adjustible, Windows based, software nightmare??? Then, they put on an EGR system that is completely unnecessary and the EGR valve is in the worst possible place to service or test!! Rant off ... That is all
