where can you buy a 1999 Cougar V6 IACV

The one ive ordered now will be the third different one ive tried now so ive only got one more choice if this one doesnt work :LOL:

Im not getting moosing now the car just sounds like a lawnmower at low speed
 
it did have but was removed when I fitted stainless headers, Gem's cougar has had the EGR blanked so there is no pressure from that point in the system (nice thinking though (y))

Do you know what the model number is for your 220 one?


I can't find a definite source for the number but the 220 one has 'squashed' hexagonal shaped ports, not circular ones.

Does Gem's Cougar have the smaller LIM?
 
Interesting point on the earlier engine

Although it has 2544cc the handbook states it as 2495cc

Did ford not notice they had extra power to start with ?
 
Dan, what was the print date of the handbook?
It's generally accepted the smaller cc engines were only fitted to C2's.
The reduction in cc was 'enforced' by Mazda's use of the same engine in their MPV and the need to meet Japanese regulations that restricted the engine size to less than 2500cc.
 
The handbook date is on the back cover, bottom right, and will be something like: RHD 6/98-1 en.*

* this one has the cc for the V6 as 2544. (y)
 
Rightly or wrongly I've been running my C1 without the IACV connected for the last few months. I tried cleaning the old one without much change. I bought a replacement from Ebay but that was not good either ( no idea which version I bought )
I decided, that whatever was giving the signal to the IACV must be shot and therby be stopping the IACV from functioning correctly.
Running without means a little bit of heel and toe when the engine is cold to stop her stalling but other than that she seems fine.
I will add there feels to be a fair bit of movement in the engine, I've not yet investigated but unless I go on and off the throttle gently from the drivers seat it feels like the engine is rocking a fair bit, I've just taken her off the road for the winter so maybe I'll investigate a little, maybe the mounts are shot. And finally forgive me If I've hijacked the post but IACV, seems I can live without it, don't all shout at once but feel free to correct my ignorance. Mabo

I tried running without the IACV connected when I was troubleshooting and it would just die out on me.

Only thing that would worry me about running it with it disconnected is would it have an effect on the other parts of the system that run off the pressure from the engine , such as the brake servo :oops:

I'm not even sure how that's starting at all. At a guess you've got enough coke on the throttle butterfly that the engine can barely idle. The heel-n-toe is keeping it alive.

Yeah, that'll be the lower roll restrictors I should think. They can get pretty bad before you really notice them.

That's what I would expect. Assuming the rest of the inlet tract is in order, I would expect it to start, sputter, and probably stall.

Well, I'm sure you wouldn't actually drive it like that.

It sounds like our friend here is doing that, is it not having an effect on your braking system not to mention what else it could be damaging?

You say you may think its the connection to the IACV thats given up, have you tried checking the connecter with a multimeter?

If you have the later engine I have an IACV you can have?
 
Does anybody know the finis code for the bolts that hold the IACV?

Never mind ive found a breaker thats got them, after having to send them a picture of what an IACV is :LOL:

Good try Mako but not true. The ST200 throttle body and lower butterflies are pretty much spotless. Running ST200 upper inlet, throttle body, tubular exhaust manifold with out that horrible "put exhaust fumes back in the top of the engine" link, Got the main Cat in and if I remember rightly a blue flame twin tail pipe zorst system. Most if not all bought from your good selves on this forum.
Needs barely any heel and toe, within half a mile she'll tick over fine. And with regard to "well I'm sure you wouldn't actually drive it like that " Sure am, done around 3 or 4k in the last few months and enjoyed pretty much every second. Even got the average fuel consumption up to 34 !

See my comment just above !
 
Oh dear Mabo :-( if your iacv is disconnected but your car is driveable you have a rather big problem! Unless of course you have just disconnected the wiring to it in which case it will be either stuck open or stuck closed depending on whether you have the spring type fitted
 
Well Finally my iacv WITH SPRING!!! Has arrived from the usa.

Will get around to fitting it this weekend and report back with the link to where I bought it if it works (y)
