$23 for a Canadian EGR Valve from Amazon (I got the last one), shipped free with Prime, vs $80 from Rock Auto for an American one plus a gasket, plus shipping.
Yes, I think the diagram is correct, but basically the way it works is C and D are always powered: A, B, E, and F are grounded to actuate. But you are going through a sequence, so its like: B, A, F, E, B, A, F, E, B, A F, E etc, to go one direction and then it would be E F A B E F A B E F A B to go the other, but there are 24 possible sequences and I don't know which is right.
Oddly, I've found a couple really good deals on the Canadian EGR valve (new), so I'm just going to buy one. I presume you can just plug the hoses and not worry about them, or hook it up as shown.
I do like your SST.
....I found that the idle was low and rough. After driving 20 miles to work, the idle seemed to be stable at 700 rpm (I think it used to be 800). Driving home I had it stumble a couple times,...
Well, I got the EGR, its definitely the Canadian EGR valve and even has a Mazda Genuine Parts sticker on it, very complete.
So did you hookup the tubes and stuff or just leave em hanging ??!
(Or is your original EGR still working ???)
