Took my car to our mechanic to see if there were any vacuum leaks or anything causing my rough idle. He said that the car just ran really rich, and there were no codes for it.
check your injectors.. if they are our of balance you could have problems.. bud of mine had one running 60% more fuel than the other 7.... After taking care of that his car ran like a champ... the problem only started after H/C/I install so we figured it was the computer not happy with the cam and stock torque convertor...
