Hello. If the engine is shaking that bad and has no power, then it may have a bad misfire. This can be caused by a bad spark plug, but it can also be caused by a bad sensor such as the air flow sensor. These need to be checked as well as the other sensors.

If the engine is lacking power also then it is possible that the catalytic converter is failing also from the misfire. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the shaking and loss of problems. From there, they can move forward with the correct repairs.

Q: Car jerks and stalls 1994 Oldsmobile 98
