I had the dealer perform the valve lash adjustment and do the auto trans service last week. Now the idle seems to be a bit weird. When in drive, it seems to idle a tad rough. And when I'm at a stop light, and I start to let off the brake to go, it lurches forward. Before I take it back to the dealer, has anyone experienced any of these issues or has any clue what it may be? No check engine light and the valves are very quiet at idle.
