my car gives a CEL p0100 and p0420.
it is running EXTREMELY rich and sometimes stalls when idling.
i have checked the MAF and it is good.
i also tested the injectors and did a compression test on the engine and they check out.
O2 sensor is good also.
what else could i check?
i am getting about 5mpg!
my car is a 99 gsx with injen intake
