I recently had a coolant leak that, as I was told by my mechanic, got down into the plug wires. They've replaced the plug wires, I've replaced the two coil-packs, yet still have an issue with the engine where, intermittently under load, it will have a consistent sputter. Almost like a misfire. There's no clanking sound, but a repetitive sputter and noticeable loss of power. Sometimes, it will run just fine randomly while driving, but most of the time it will have the sputter issue.
My guess is the plugs, which I will replace, but what else could it be? Dirty MAF? Thanks.
