My 97 intrepid is idle to hight - 1997 Dodge Intrepid

I'm guessing this Intrepid is a 3.5 cause I have never had this problem with a 3.3 But what I found what always caused it in a 3.5 is bad intake gaskets allowing more air to flow into the engine. Change both upper and lower intake gaskets and this should fix the problem. However when changing the lower intake gaskets there are two bolts that are probably gonna give you problems. The one closest to the front and the one closest to the back. They are the bolts that hold the intake down and go into the head near the coolant ports. These bolts are probably going to break off. The good news is they most of the time break off and there is still a lot of bolt left once you get the intake off to get a vice grips on. Have a torch with a good heating tip handy and someone that really knows how to use it and heat the cyl head around the bolt and then try to get it out with the vice grips, but be very careful cause heating aluminium can be very tricky too much heat and you ruined the head.
