hello i have a 2003 ford taurus with a 3.0 duratech v6 and it runs great it has 175K on it. but its been throwing a p1506 code and all that i can find is the it means high idle and it idles around 1,200-1,500 rpm’s and i changed the throttle position sense and the idle air control valve. and cleaned the throttle body the mass air flow sensor i had it checked for vacuum leaks and i had all the parts and electrical circuits tested and it all tested and looked good. but the other day i ran seafood through the vacuum lines and of course the exhaust was smoking and blowing away from the car and it was smoking a little bit around the engine it was coming from the bottom and i think i might have an exhaust leak but I’m not sure please help me!!!!!!!!!!

I would start by getting under the car and looking for starters. Check all that out with a flashlight. You may have a problem there, so you might get lucky. BUT, in my experience I would get ready to do the intake gaskets, as well as the PCV. This is a common repair on these cars. Especially at that mileage. They also can be a PITA.

Seafood through the vacuum lines? Seems kind of fishy to me. Talk about stinky exhaust. But you could have an exhaust leak. As noluck suggested, look underneath for starters, you should find at least one. Look for the potential exhaust leak as well. If it’s before your o2, your sensor will be off. But that’s no excuse for high idle. Is the idle air passageway clean? And certain of no vacuum leaks, have another look for those
PS. I know you meant seafoam.
