Hey Ryan, here's a weird one for ya, maybe it's just because I'm paranoid, but figured I'd ask anyway...

Engine runs fine, but it shakes. I know there are 4 pistons and a lot of other parts moving when it runs, but it's a very noticeable rumble - when my stick is in neutral, you can almost watch it shake back and forth. Again, I might just be paranoid, but I'd kinda like to find out why it's doing this. I suspect some sort of build up on the 1st or 4th pistons, you think a compression test would help me out any?

[Ryan]

A compression test would be a good place to start. You can also visually inspect the front and rear engine mounts. If they've decayed enough they won't stop the engine from moving like they're supposed to.

The stock idle spec is somewhere around 700 RPM IIRC

So Im changing my alternator out, and I've removed the bolts, wires, connectors and what have you. Just wondering how to get the alty out of my engine bay. I've got the b6 DOHC, there doesn't appear to be enough room above with the AC and PS lines, and not enough below with the catalytic converter in the way. Do I have to remove something else? Am I a complete dunce and am missing something super obvious?
EDIT: Figured it out, had to muscle some vac lines out of the way, now just gotta figure out the vac line plumbing.

[RobMinhas]

So I finally figured out my vac lines, huge pain in the a-- but with some day light I managed to do it fine.

New problem though, start car and it dies right away.

Seems like when I was dicking around with the vacuum lines I managed to unseat one of the injectors, when I started and revved it to try to keep it going but maaad smoke came out of the tail pipe that smelled like fuel, i killed the engine and took these pictures of injector 1.


And the same smoke was coming out of that hole, this makes me think that the fuel is being dumped in there and is escaping from there and that the combustion chamber isn't holding vacuum causing the car to stall.

I ran out of light today so I won't be able to tackle it until tomorrow, but how would I go about fixing this? Is that injector damaged? Is it as simple as unbolting the fuel rail and bolting back in?


EDIT: NOw I found this video here, http://www.youtube.com/watch?v=hEIP9ZYnnRc , it says to turn off the fuel, but can anyone tell me what exactly the "fuel pump relay" is and where is it connected? I found the procedure to do it here: http://mx-3.com/manuals/showimg.php?fil ... F1-113.gif but it doesn't say where the fuel pump relay is.

EDIT2: I'm stupid, I confused fuel pump relay with fuel pump solenoid, I still don't know where it is though other then there being a "Passneger wall" that must be removed as per http://mx-3.com/manuals/showimg.php?fil ... F1-120.gif Anyone know where that exactly is?

Look behind the center console on the passengers side. The ECU (a flat silver box) is there with a black relay connected to a bracket. I believe that's it.

Oh ok, I'll take a look tomorrow after class, makes sense though.

Quick question:

It supports the radiator of a Mazda Protege 90-94 in a B6?

Other versions I can use to my radiator B6, because I need to change mi radiator Asap.

[Dustinlib]

do the driver's side axles for the f series and g series interchange? I know the passenger's side is different.

Hey quick question, which type of HID kit fits the mx3? Is it 9004?
I know its probably somewhere on the site but honestly I can never find anything with the search thing

[Ryan]

Which way do you turn your key to unlock the driver's side door?

Counter-Clockwise?

[wytbishop]

yes
