i did some searching but all i see is things to do if your throwing a code. i have an a6 block..11.5to 1 cr. z6 head and an a6 intake. im using a p28 and a 4 wire o2 sensor. engine throws no codes(musta done somthing right ) after the car warms up it gets a very fast idle drop, 500 to 1000, up and down ,up and down .. etc... i sprayed alll my lines with starter fluid and nothing happend so im assuming my vacume system is good, car did not do this with the a6 moter, any help on this would be great
