Ford exhaust manifold leak - no power
Ford exhaust manifold leak - no power
Would an exhaust leak at the exhaust manifold to cylinder head conjucntion cause an excessive loss of power upon acceleration?
Re: Ford exhaust manifold leak - no power
No, an exhaust leak would not cause a bad loss of power. It will cause of course a noise and can effect the reading of the oxygen sensor on that side. That can effect fuel delivery, but would not cause an extreme loss of power.

Thanks Scotty, I think I found the source, open vaccum port on intake manifold, however, still misfiring.
Re: Ford exhaust manifold leak - no power
A vacuum leak would not cause a loss of power. That will just give you a rough or high idle.
If the engine is misfiring, check the basics.
A bad spark plug.
Plug wire.
Ignition coil.
Cap and rotor (depending on year).
Low fuel pressure.
