Ok so your car is running to lean. Now this can be caused by a number of things so you need to determine what might be causing it. It could be a bad EGR valve or a vacuum leak or a carburator adjusted wrong or bad O2 sensor telling the car to lean out and so on. So do you have a digital multi meter? Is you car carb or injected? Get back to me and we can go from there.
