my car is running too rich at idle, what could be the problem? it runs fine at any other RPM's but when i was at school and used my car for the demo it was running very rich, i was thinking maybe it was the fuel pressure regulator. or could it be the ECU? because im using the stock OBD0 ecu with a 95 B18B1 motor in the car.

let me know if you know what it might be

thanks

 

Stock injectors also? Do you have any engine codes?

 

B18A1 injectors, was throwing a code for speedo cable but fixed that, nothin else it popping up

 

How do you know it's running too rich?

 

when they put the sniffer if my exhaust it had a high emissions reading because of too much fuel

 

some one has somethin, help me out please

*BUMP*
