wilber15 you are so correct. I probably would have saved money,BUT the dealers here in the Richmond, VA area have not been so friendly or affordable. Plus i really enjoy working on my own vehicles. I buy a few vehicles a year and try flipping them after making a few minor repairs. These F150's are great trucks easy to replace parts on anyhow. Is there anything I should be paying special attention to that would have caused the converters to go bad other than spark plugs,fuel injectors and COP's. Thanks
