Hey Guys, Price sounds ridiculous if the plugs do come out! Motors Flat Rate Time is 1.8 hrs at that dealer labor rate. Performing a fuel induction service is a good idea beacuse the actual cause of this problem is the carbon build up in the chamber aroungd the spark plug and threads. A fuel induction service will clean alot of this carbon and lessen the binding on the threads of the plugs in the head. This fuel induction cleaning is a great service regardless becasue it will help clean carbon build up in ports and on backs of valves and improve fuel atomization and flow. The carbon build up on the intake valves will actually soak up the fuel charge and cause hesitation and stalling and poor mpg. Back to the plugs , look at the tsb i attached and see if your tech wants to go through this. I dont think so, it is a real drag and access really sucks so i feel most Techs are praying that the plugs will come out and not have to go through this tough procedure. Please note that the bulletin labor time on this is "Actual Time" and doesnt even have a stated labor time because it is so complicated and tough. even with the special tools it is a b?/ch . So i do feel that a flat fee of $40 per broken plug is reasonable. The plug wall is so thin that they cant take much twisting on stuck threads. Again find a expert tech that you trust and who has these special tools if you have to tackle this. By the way i havent been a tech in 25 years I run A service and parts dept with 15 techs, Not all of my techs would i put on this job. good luck. Jim Sorry the TSB is too large to upload to the forum please search and acccess TSB 08-7-6 for all the info and tool information file is 497kb. I can email it to anyone who needs it. Jim
