yesterday as I was coming home, I stopped at a red light and my rpms started to jump from idle and the car felt like it was going to die. What could it be? I cleaned the tb and filter like 5000 miles ago. could it be my coil packs? Also sometimes out of the blue my engine vibrations become very powerful and I can feel my whole car shake violently and it lasts for about 20 mins and goes away. Any ideas? THanks

 

give your car a tune up......and check it for codes.....make sure your idle RPM is good...im thinking it can be ur plugs.....but yea....a tune up could be good if u havent done one in a while.......

 

did the plugs a few thousand miles ago but will check again, any other ideas peeps?
