ok so here i go,it has a 5.7 liter,auto trans,i brought it to the shop because everytime it is put in gear or while your sitting at a stop light the idle drops down to around 100 rpm's on the factory tac and when you go to take off it bogs and almost feels like it is going to die but then you get going and it seems ok until you stop again.i had a code 32 and the egr was replaced.no code 32 any more but still the same thing the guy at the shop had it for 2 whole days a could not find anything wrong.any help at all would be greatly appreciated .
