97 Neon Idling Rough

  • 1997 DODGE NEON

I recently Purchased a 97 Dodge Neon (auto) which now has 101k miles on it. Recently I ran into a problem while driving to work which turned out to be a blown spark plug. This did not damage the threads, however, once I replaced and gapped the spark plugs the engine began to idle very rough and the check engine light came on. When traveling at highway speeds the car seems to run fine. I have also noticed a decrease in the fuel economy, 30mpg down to about 25mpg, and there is less power when accelerating. I brought the car to a mechanic, he checked the engine codes, and ended up replacing the fuel sensor. The car ran fine for about a day and then the same problem occured again with the check engine light returning. Every time I start the car I have to encourage it with a little gas otherwise it does not start. I have checked the forums and have found little help in remeding this problem. If any one could help I would appreciate it. Thank you

Do you
have the same problem?
