I am getting bad gas mile on a 2005 ford tarus how can i tell if it the fuel injection going bad
When was last time you had a tuneup ? Check air filter and replace if necessary, clean throttle with throttle body cleaner, add fuel injector cleaner to gas tank and replace fuel filter.
A check engine light will be the first you will see, if you do not have a check engine light then do what firebird recommended.
If check engine light is on have the codes read at a local auto parts store. This service is usually free. Post the codes here and we will see if we can help.
