Engine sluggish no power...
I have a 2001 Mustang 3.8 and I had the engine rebuilt and then I tried getting it running and replaced a lot of sensors. Still couldn't get it right..
I put some seafoam in the engine and I realized that the whole engine compartment was with white smoke.
I took the exhaust manifolds off and found a inch and a half slit on the driver's one near where the exhaust pipes bolt in.
Then I sprayed some carburetor cleaner inside the tubes of the exhaust manifold and found that the tubes were leaking out the flange around where the tubes molded with the flange.
I I went to my local Pick-A-Part and found a good exhaust manifold, $39.95 and put it in and the 3.8 Mustang "runs like a bat out of hell" now.
Maybe something like some poorly manufactured exhaust manifolds are putting some of these Mustangs in the wrecking yard.
I was born in 1950 and I've watched America go downhill since the 1960s and 70s, there's no Integrity anymore just a want to grab more and more money.
I'm finding out that these 1990s and 2000s Mustangs are poorly manufactured and designed..
I have been a dealership mechanic off and on since the early 1970s and I also have an electronics degree and have noticed that cars are made to throw away real quick so you can buy a new one.. we need to bring Integrity back to America Make America Great Again.

I hadn't a power loss and it was the exhaust manifolds leaking.
I have a 2001 3.8 and I had rebuilt the engine and I never could get it right, I put on all sorts of sensors and checked things, couldn't figure out why that had a lot less power. I found out there was a hairline crack in one of the exhaust manifolds on the driver side. This would change the way the oxygen sensors sensed.
I also found that some of the pipes that go into the flange we're leaking where they were pressed together. They should have welded them.
I went to pick a part and got a decent exhaust manifold and it has plenty of power now.
One way I checked it is, I put seafoam in it and the engine compartment was full of white smoke. Hence the leak.
