Excess fuel
I have a 95 eclipse with a stock motor, cold air intake, and a cat back exhaust. The problem i am having is their is raw fuel coming out my exhaust at an idle, and when you rev the motor it really dumps it out. Any suggestions on what could be causing this would be appreciated.

Re: Excess fuel
Welcome to AF
What motor is in the car? Is it turbo? Do you have a CEL. I would be checking the fuel pressure and front o2 sensor first.

Re: Excess fuel
It is the 2.0 non turbo, the 420a i believe, it just started doing it the other day and have no clue why. If it is a fuel pressure problem what psi should it be at. How would i check the front o2 sensor.

Re: Excess fuel
Fuel pressure should be around 45psi. There is a test port on the end of the fuel rail where you can test it at. If the front o2 sensor is bad you will get a check engine light.
