I have an r32 gtst, all stock except for a 3'' cat back... Right down to the factory airbox.
It runs perfect, idles perfect, revs perfect. It had some pretty nasty misfires under load after 3200 rpm, so I dropped in some new NGK copper plugs (until I get all the bugs sorted out), and some used but working OEM coilpacks.
Now there is no more misfires, car still runs and idles like it is brand new, except at WOT the car pulls strong to 3700 rpm, then the power band stops pulling and just flatlines until 5000rpm where it takes off and starts pulling strong again.
There are no more misfires what so ever.
Where would you start?
