I put the E-303 cam in my 5.0L about 3 months ago, got the car running great. Couple weeks later I had to put in a new idle air control valve due to a surging idle. Now my car will start and run fine, but when I put it in gear (automatic) and the rpm's drop, it just dies, but if i give it some gas while putting into gear it will go just fine. It does this every time now when I stop the car unless I put it in neutral. Car idles about 800rpms and was idleing about 650 with it in gear before. Anyone have any ideas?
