welcome to 2carpros
if you have engine light "on" scan the pcm for code(s)
The engine is misfiring and we need to know what system is causing it.
You did right thing to change the plugs, but you should replace the spark plugs wire too, sometime they break in their boots.
Misfire could be caused by loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression. Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Provide me the code, I'll help, or let me know if there is no code.
