Ok gy's I can no longer deal with this issue it has gotten worse over the last week or so. What happens is when I start the car it will idle very high for the first five minutes then it will back of a bit. The idle screw has been adjusted all the way out so there is somthing else going on here?? Somone had said somthing about a part in the egr going bad that will cause this? Maybe some sort of diaphram leaking??
