Would getting a new O2 Sensor when my check engine light was tested and they said it was a sensor but didnt say which one would tht increase my gas mileage cuz right now its at like 15mpg and I also need a new Ignition Control Modual would either of those have anything to do with it tht would give me like 10-15 more mpg?

thanks


I got a 1993 2.3L LX Mustang Non Turbo just incase you was wondering

yes, when your ignition and o2 sensor goes out there is no way to regulate fule, so it will dump as much as it thinks it needs. replaceing those will DEFINATElY help you out

ok if i replace the inition control modual would tht do anything or would i be good just doin the O2 because its only 43 and the ICM is 120

Have the codes pulled from your computer and see what is actually bad before spending the money on anything. Its worth it, unless you just want to guess and waste money replacing parts that don't need it. The icm usually makes the tach act wacked too.
