Check Engine LIght Code 14
 

Just had the intake maniford off and changed the old vacuum hoses. Now the car is running rough. Checked the codes and get code 14, fuel injector number 1. Which one is number one? The connectors are on tight. Did I miss an electrical connection? Any ideas anybody? It's a 92 by the way.

Thanks

Also, car has been sitting for a couple of months with less than a quarter tank of gas. Don't know if this would make any difference or not.

Figured out the problem. The engine harness connectors were not connected fully. They both ( the gray square plastic ones ) have a rubber seal inside which can get out of place and prevent the connectors from connecting fully.
