Well, I'm thinking about putting some money into my 1992 Mazda MX-3 GS and am kinda wondering where I shall start. Everything is stock of course but wanna put a new air intake on it but have no idea what would look good or fit for a decent price? Also, does anyone know where I can buy some performan...

Wait I was talking about the hose that comes out of the intake mani and goes past the Cyl 1 spark plug wire

Yeah I looked down it and the hose looks in good condition besides being stiff, what is the green circular thing it plus in?

:crying: Ok, I thought I found a vac leak (one of the vacuum chambers had a plastic piece that a hose plugs onto that broke off and I JB'ed it back on) but still hear hissing around Cylinder 1 in that general area but can't pin point it. Should the two solenoids that sit on the back of the engine be...

Ok I found its spot! Its on some black thing that sits below the solenoid, does that come with it if u buy a new one? The plastic piece the hose goes over actually broke off inside the hose

Ok, so i was trying to figure out if I have a vac leak (I can hear hissing sound) and saw this but have no idea where it is supposed to be plugged into (if anywhere? ) It comes out of the block between cyl 1 and 3 as shown in the pics: http://img844.imageshack.us/img844/1283/21707812560882085024910....

What do I need to use to jump the TEN and GND to put it in diagnostic mode? I looked in the manuals and can't find anything over this.


::EDIt:: found it, nvm

I wasn't able to adjust the idle and make it stop (it kept doing the same thing). Someone mentioned to me though that if I unplug the IAC valve and turn the car on and the surging stops, it is the IAC going bad. I drove the car with it unplugged and the car drove like s--- (of course) but never did ...

Nah the idle raising isn't much of a bother, just the surging. Any clues to what hoses are vac for brake system?

Yeah I ended up finding it my Chilton manual. I am simply at a freakin' loss to knowing what the hell is causing this surging issue with my car. Everything I think it could be turns out nothing and some don't make sense. I don't understand why it'd simply go from 700RPM at idle (only when car is in ...

Ok, my main goal is to see if it is faulty, because my idles are surging (but only when clutch is down)

Where is the MAF located on a 1992 MX-3 GS 1.8L? Also, what is a good way of testing it?

Nah I didn't wiggle any of the hoses but should of, maybe ill try it later. Nope, no codes either (i wish so it'd make this easier lol). I was just thinking if it was a vac issue wouldn't it cause rough idle and wouldn't be so specific? could this be something with my brakes? I just dont get why it ...

I went out and even sprayed Carb Cleaner on stuff and no change in idle and listened for any leaks and looked at hoses and can't identify any leaks. It doesn't help the manual page for the hose diagram for vac is extremely compact and barely can make out what hose is where.

yeah idle sits at about 700RPM without in gear
