While I was accelerating and entering onto interstate 80 at a speed of 50mph I heard a loud pop and lost power. The engine continued to run but with a great loss of power. I continued to drive at a moderate speed until I could get to a monroe service center approx. 20 miles. The #7 plug for the second time blew out of the head. The repair cost this time was $294. 38 and the engine light is still on. It's been eight months since I had it repaired the first time. The #7 cylinder is now misfiring even though the plug has been replaced. Mileage to date is 200,892.
