Hi all i have a few questions i hope can get answered.I have a 96 neon 2.0 sohc thats running rich.I have changed the fuel filter,pcv valve,plugs,and went through about 2 o2 sensors the maniflod ones.It will run fine for about a day then the gas milage gets eatin fast and the service light will come back on.when i change the plugs i can tell theres a ton of fuel being pumped there covered.I have gone through 2 02 sensors allready as i have stated.And the oil is very fuel contaminated.any suggestions or advice would be great thanks

 

Check Engine light?

i had the same problem and did everything you did and it turned out being the coolant temperature sensor ( i have a '96 SOHC also).

Good luck

 

Yes check eng. light comes on if i change the plugs and o2 sensor on bank 1 the light goes out for about 1 day.Then comes back on il have to check the temp sensor and see if that helps thnx for the suggestion neon15

 

I'd also inspect the wiring to the O2 sensors.

 

Go to autozone or somewhere and have them run the codes
