It really wouldn't be recommended due to the timing a misfire can mess the timing up which could result in well needing a new motor...11$ for a plug or $1000-$1500 or more for a new motor your choice

Brakes Plus checked the engine and found a lose wire, attached it and all is solved. Thanks for your concerns. Kennie
