Talking Po446

Hi All:

My '98 SE with 171k is running fine, no issues with acceleration or power. Check engine light is on and scan returned PO446. I think there is a mild raw fuel smell at start up and wonder if you could send me in the right direction for repair.

Thanks,

-Jay

check the vacuum lines first. there is a boot on the throttle body that one side goes to the purge valve and the other the fpr. that being cracked is a common issue. also the metal ones that go to the canister are bad at the transition to and from rubber
