new boxster owner with engine problems

[murphy228]

Hey guys getting the car back to day thank god. They told me they changed the coil packs and plugs. Reading through the paper work with the car the coils have been changed three times so this is the fourth must just be the weather like suggested.
Thanks for all your help

how it goin guys posted last week to ask bout my engine problem as you might have read got the coils and sparks changed so car was running good again.
just last night since being fixed heard a high pitched screech from what sounds like inside the exhaust. only heard this when i reversed into the drive with the window down. it occurs now when between 0-5 mph and when idling just wondering if this is linked to the coils failing or if you've got any suggestions to the problem cheers
