Help, please. Check engine lite went on yesterday. Disconnected battery and lite turned off but now ESP lite is on. Not too worried about this but now my car is vibrating and sputtering. I hear some air blowoff coming from the drivers side intake plenum in a cadence manner. I had slight engine shudder prior to yesterday (mounts on the way) but now it is bad. Any input is graciously welcomed.

Just popped the hood with the engine running. The intake plenum was disconnected and the entire engine is shaking causing the car to shudder. I guess the mounts are in worse shape than before. No more driving till the mounts are replaced (I love chatting with myself).

BTW, could using 5-30 Liqui Moly engine oil have a negative effect on engine performance? Just had an oil change about 2 weeks ago.
