I was driving my SC 2.0L down the highway WOT. I looked down at the speedo, and noticed that I couldn't get over 100mph. I let off the gas and started having some serious problems. Burning massive oil and misfiring something awful. I made it home and downloaded my ECU to find that my #1 and #3 cylinders were misfiring like crazy. Question being, is this going to be a blown headgasket, or possibly just the piston rings on the 1 & 3. Also, does anyone know about beef ups for these parts, so it doesn't happen again. PS, I've only got about 55,000 miles on this engine.
