It wont idel and dies when it does on 2000 Dodge Grand Caravan

It ran fine when it is first started but when warm it backfires thru intake and exaust so I replaced the cam and crank sensors and the problem got worse. I also replaced the idel controle assembly. It is worse then before. The PCM has maybe 1000 miles on it.

stop... you are replacing parts for no reason. go get a real diag and a bid for repair it may be a simple fix instead of all the parts you are suggesting
