Hi, I've been having the same problem with this car for maybe a few weeks now and cant figure out what it is. I checked all the vacumm lines and I cannot find any that are ripped or have come out. Today i cleared the check engine codes to see if anything would come up and to see if they were legit codes. I drove 10 minutes and I got P0420, P01705
2002 nissan sentra gxe 1.8L automatic
THE CAR HAS THE FOLLOWING SYMPTOMS
IDLES UP AND DOWN IN PARK AND NEUTRAL FROM ABOUT 1525-1825 RPM
IDLES HIGH MOST OF THE TIME USUALLY IN PARK AND NEUTRAL IT IDLES STABLE AT AROOUND 1500 RPM
NO POWER. I FLOOR IT AND IT TAKES LIKE 5 SECONDS FOR IT TO PICK UP
SOMETIMES WHEN I PRESS THE GAS IT BOGS DOWN AND ONCE IN A WHILE STALLS BUT USUALLY THE RPM SHOOT UP
THESE ARE THE SYMPTOMS IVE NOTICED. IT JUST STARTED HAPPENING
ONLY THING CHANGES WAS SPARK PLUS WITH NGK IRIDIUMS ABOUT 2 WEEKS AGO BUT THE PROBLEM HAPPENED BEFORE THIS.
please help. Thanks
