Went out to start my VC this morning, and it was a hard idle, really rough sounding. When I shifting into reverse it hit the gear very hard, so much it shook the whole vehicle. And then I had no acceleration when I pressed on the gas pedal. Shifted hard again into drive, and into park. Shut car off and tried a few times and it resolved. Check engine light came on is staying on after flashing a few times. Still trying to find a solution.
When cold, the engine has to be cranked much longer that normal and seems to start quickly when key is turned off and the engine is re-cranked.
