i just replaced the coil in te car as it had went out. i test drove the car and no problems, and starting yesterday the car when you let out on clutch all the way andd start to give it gas itll start jumping vibbrantly like you just let out the clutch without giving gas. it does it in 1st, 2nd through 3rd about 25-3k rpms. its also hard starting as you have to sit and crank for like 2-3 mins and give it gas and it finally start. got to the house this morning and put the scanner on it and it has codes cyl 1,2,3,4 msfiring and something like catalyst system low bank 1. note before i changed the coil the car ran fine
