About a month ago the car started rattling in the back just your normal vibrations in the plastic areas...around speaker covers then the floorboard started knocking... i checked exhaust it was rubbing on the frame (speed bump) well i had everything re-done.... didn't fix the prob. Still a knock in the floor board you can feel it when you start the car almost like its skipping as it cranks .... hard to explain.... also 700-2000 rmps in first you can feel the sluggish feel...

Hard to explain but if anyone has suggestions please advise.



new clutch about 6 k miles ago.... new plugs, boots, 2 new coil packs within last 2-3 months....bought predator about 2 months ago other then that nothing has changed. I didnt change anything on tuner except timing
