The Gen II 3800 Engines have a HORRIBLE ISSUE with the INTAKE. They are made from Plastic and Warp. Waiting for the Engine to Get Hydro Locked (Coolant in the Cylinders)

i took my car to NA Auto Repair they did a great job at very resonable rates

If the light is on the engine computer will have a trouble code or codes, which may help you towards solving the problem. Have the computer scanned for the codes. Go from there. Good luck.

i have a 98 buick park avenue
i got a problem running it. it start but when i hit the break pedal some light comes out the direction signal and it shuts off i check all the fuse

Only able to clear codes with a scan tool ..Or wait for the car to see a temprature difference of 80 degrees 40 times without a fault and the light will go out on its own,( cold to hot) also known as a drive cycle without a fault. Its quicker to use scan tool..

you will need to contact your local buick dealer, and give them the VIN and some info off of the radio.

EVAP is for Evaporative emissions control system, so no this is not EGR, that is Exhaust Gas Recirculation system, as far as the P1665 goes it is related to the other trouble code P0440, u will need to replace the EVAP system Purge flow control solenoid. This should correct both problems after u replace the part disconnect the battery for 5 min's to reset system.
