New Ford Cougar owner 2.5 V6

Regarding the moosing... I always thought that was caused by coking from the EGR. As in, blow-by gasses deposited carbon in the valve.

And that was true for Tiger (my first V6). Flushing the unit with brake cleaner definitely stopped it...for a while.

But Sally - who doesn't have the EGR system - has started doing it now, at certain revs and very specific temperatures. So I think that the valve-cover breathers are just as guilty, dropping poo in the inlet. I've got an oil change in the near future, and will flush those hoses out at the same time.

Not being particularly scientific - it was a bit warmer here today - but after the oil change and blowing through the breathers, no more moose.

I think the circumstances for it happening are very specific, but are probably worse when you get close to the car needing a service.

That's my experience anyway.

Hiya, and may I be (possibly)the last to say Hi and WELCOME to the forum. It's nice to see another frosty silver car as we do seem to have a lot of black ones at shows. Although you probably know this already from your Probe days but remove the dreaded sponges from the inner panels to help it stop rotting from inside and like the man said make sure the subframe is good as they are pretty much unobtainium today.

Driving home last night and when I put my food down loss of power...eased off and it was fine. So weird. Quick Google suggests either the IACV or a fuel pump issue? Anyone else had this? Now I'm concerned if I drive it it'll lose power. Engine sounds fine...just when I pedal down it feels like it's either blocked or something.
 
As Quicksilver said. Fuel filter is an easy fix and a very good place to start.
More likely filter than the IACV, mine hasn’t worked for years and I don’t have the problem you describe.
