I swapped injectors! Wow what a difference in even just the start up and idle. So much quicker and smoother. The old injectors had soo much carbon and crud caked on them. I looked in the ports and much the same. Any suggestions on how to clean that out without knocking it into the cylinder? I'm afraid to actually look into the cylinders.
Oh, its and 89 4.0, and 19 lb. mustang injectors.
