...engine light came on. Help!!? I hit a pothole in NY, hard, swerving to avoid a cab in the Bronx. The car ran fine, from Friday to Sunday, then I saw the speedometer not moving. Right after that registered, the check engine light came on. The car is running fine. I can't do anything about it til Thursday, so my question is, is this going to be expensive, and will driving it the 9 minutes each way daily (no highway) make it worse?
