The engine light came on a few days ago and I thought it was to not turning the cap 3 clicks. Figured I go by the mechanic a day or two later to reset it. The next night, I start the car up and I get a Christmas tree of lights on the cluster when I put into drive. I move the car a little and it bucks like a bronco and I get a huge triangle on the dash that basically said “game over”. Shut car off, started again limped it 10 yards back to my parking space.

The next day, I start the car up thinking I could get to my mechanic (1/4 mile from house), and everything is perfect. Bring by mechanic and said it could be from low battery. Check battery and it is strong as could be. Check the codes and there was a throttle problem and something else… No kidding about the throttle. The car revving about 1100 before it just laughed at me the night before…

4 days since then and no issues…

Gremlins!
