"I replaced the heat shield on mine "

Hi WolfeJeep - (thanx for the reply) Unfortunately the shop that replaced the Valve Cover did not mention the Heat Shields? My fault for not following up. I can tell you that; (after running the AC on a 50-80 mile drive), it starts to run a little rough. Could you tell me how difficult it is to replace the Heat Shields? Does it require dismantling the rail and pulling out the injectors?

Thank You! :)
