I have a 1994 Chevy cavalier I just change the spark plugs and spark wires for no reason just to make it run a lil better the wires are in the right spot the gap is correct the plugs and wires are all seated correctly I did not install them incorrectly so please don't try to tell me to double check I have already my grandpa says it is a bad coil lack but I don't know how much I trust that since the car was working perfectly before I changed all the wires and spark plugs and the spark plugs and wires are the right kind now my engine kinda sputters and shakes and hesitates when I start it I've also lost quite a bit of power any ideas on what's wrong I'm open to any advice here
