My 2003 ls v8 has 97,000 Its started running rough 2 weeks ago,so I took it in to a local Mechanic.He replaced the 4th coil pack and sent me on my way.problem is it didn't fix what was wrong.The engine light came back on He then told me he was gonna have to charge me 200 bucks to figure out what the problem was....I'm out on that Idea he spent Three days messing with it.then tells me he's gonna hook a wire up to my computer then to the coil to see if the harness or the computer was bad????? I'm wanting to replace the plugs valve cover gaskets and all the coils( I'm mechanicly Inclined) Can any one give me any info on the gaskets and plugs before I jump into this project??? I'd be greatfull for any advise.....Thanks
