Hey all, I have a 1990 mustang gt. Has 99 k, has edelbrock intakes, cold air intake, BBK headers, Flowmaster H pipe and mufflers. T 5 tranny. When cold it has a rough inconstant idle untill it warms up. With in the first 2 minutes of driving it may even idle so low it dies. It hold and idle of 850 when warmed up. It also has been running very very rich. Exhaust smells of gas. Also the passenger side of the engine compartment also smells like gas when running. It does not have cats, and is not throwing any codes. Where do I begin. Thank You !!!
