yesterday i took the cold air intake off from my 98 teg and put back the stock filter box in. It seems everything alright until this afternoon..... the check engine light went on !!
At first i thought it might be the problem around the intake area, likes the air temperature sensor problem or something like that. But after i checked the engine light code, it showed code 90 - "Evaporative Emission Control System leak detected in the fuel tank area"
i took the car to the garage for inspection.....the gas tank has no leak, gas cap is in good shape, everything seems fine and it drives just like normal....

Now i really don't know what's going on on my car.....maight be the CVS valve, charcoal canister...or...etc.... does anyone have any idea?
and is it really caused by the removal of intake???

THANKSSSS !!!

 

hey guys I've checked the code today by using OBDII scanner, it shows P1457, according to the code list, it is "Evaporative Emissions (EVAP) Control System Leakage (EVAP Canister System)"

actually how can i fix the problem..? what actually is EVAP canister system ? (which means the charcoal canister needs to be changed??)..... is it the common problem on Acura/Honda cars?
