Please add info if your car has head/valve failure/loss of compression/misfiring M271


Someone mentioned this a page or so ago, but it turned out to be failed chain tensioners that caused the chain to skip a tooth and smash the valve's. $4600.
That was two weeks ago, now it's back in the shop and running rich with no explanation as to why. I'm having the service manager email me the codes, but they've had it for two days and are still stumped. It shakes hard at idle, but seemed to rev smoothly for the 20 feet I drove it before calling for a tow. Their suspicion is supercharger related on the intake side, but we'll see.
The only under the hood repair was a bad thermostat at 130,000. The engine runs as smooth and quite as when I bought it. It's been 9 1/2 years that I have owned it. I want to get a used SLK because I love them, but I'm having trouble pulling the trigger because my car still runs so well.
