Hi everyone
I desperatly need some help
2002 Gran Prix, 3.8L non supercharged
total lack of power...high idle (1300 rpm).....seems like any grade or hill...and I can't keep the speed....transmission kicks down, but engine loses speed...no power.....has slowed from 60mph to as low as 30mph
new spark plugs (bosch +4s) and airfilter about 6000 miles ago
power problem seems more recent......
changed the gas filter last week thinking that was the problem....no change
I haven't been getting a code....but checked and found po404....egr valve......changed the valve...cleared code.....
no change problem continues...and code returned
ideas please?
