Hello i have a question for you guys, I recently bought an 02 4.7l that would start but ran rough and had no power. When i pulled the injectors there were two different types some of the part numbers ended with af, and the ignition coils were not all the same part number either. My question is do they all need to be the same and if the intake breather is missing will that cause it to misfire? And the small vacuum line coming from the brake booster is not hooked up can that cause it to misfire as well?
