ok, my car had a hesitation and a miss before so i replaced whole opti unit, plugs, wires, coil, o2's and fuel filter. after that the car ran better then ever. after a couple hours i came around a corner and it instantly started running terrrible. It sounds like after i took the corner the car is only running on 7 cyl. What to do now??

 

could it be possible that i spun a bearing?

 

Did you check to see if any plug wires slipped off?

 

they all seem to be on tight
