What is this?

So... I'm trying to end the seemingly never ending saga of what is causing my Milly's engine to miss. We've been unable to really find anything wrong with it that would cause that. Yesterday, it suddenly got worse, where it actually stalled on me twice, while moving at that. It's never done that before. It still seems like its something with intake or one of the sensors. I noticed that upon shutting the engine off, it sounded like there was a vacuum effect. I had my dad listen for it to try to find where it came from. Seems that it's the air box. My dad messed around with it... Well, anyways, to finish, my dad thinks the problem could be that thing, we just don't know what it is. Do you guys know?

^^^What they said.^^^

I've never heard of MAFs causing a car to miss...maybe bog the car down and decrease performance...hesitate a bit...Try getting some carb or brake cleaner and cleaning the inside of the MAF. Just spray it on and let it dry. Sometimes they get dirty and in turn they don't get the correct readings. Like WMJ said, check your O2 sensors, also, bang on your cats with a hammer or mallet or something. If you hear them rattle, then they are broken and they could be causing backup in the exhaust which could be another cause of your car missing. Another thing, take off your valve covers and check your spark plugs/that general area...if it has oil on it or around it your valve cover gaskets could be leaking which can also cause a misfire...

Gracius, smart ones. I had a hunch it might be the MAF sensor, but hell I knew. :P

Tomorrow, I'll try cleaning it and the air intake box/hose. I'll buy a new air filter, too. I know its dirty. If all that doesn't work, I'll look into the valve cover gaskets.

Oh yeah... I've always dreamed of owning a faultless K-car. Ah... what I would give to own one of those beauties. :P

Hey, the K-Cars we had were very reiable. Never had any major repairs that had to be done to them...of course they're about as complex as a lawnmower but ya know :P

Yeah, I believe Mellenias are OBDII. I think Mazda went OBDII on their vehicles before the deadline (1996), and BV's is a 95.

:blink: Uh, I don't think you need to take your valve covers off to check your spark plugs, or even to check them for leaks.

Do you have a "check engine" or "service engine soon" light on at any time?

Yeah, I don't know how his engine is designed...I'm just going off of what I know with my car, which obviously is completely different.

Oh wait, that's right...I don't need to take off my valve covers completely to get to the spark plugs...they are set deep in the valve cover general area, but I forgot the valve cover comes out around the spark plugs...though, to get the valve covers off, the spark plugs and ignition coils do need to come off, and that's when you can see if your valve cover gaskets are leaking or not. Yeah....sorry about that BV, I don't know what I was thinking when I said that, I got mixed up in my thinking because I'm usually ripping apart my VCG's when I'm dealing with the spark plugs and ignition coils...But yeah, I don't know how your engine is designed, but look down into your spark plug wells for oil.

Forget what these other guys say. It's a Caution Box. It makes sure your engine is running cautiously. If you were to remove this box, your engine could explode from lack of caution.

At the same time, it could be working too well and causing the engine to stall due to overcautiousness. That might be the problem. Replace the Caution Box, but do so with caution. :D

No, I'm pretty sure mine is OBDI. I've already taken it to my uncle's garage many times and he couldn't hook up his diagnostic reader for this reason.

Do you have a "check engine" or "service engine soon" light on at any time?

It's on periodically, was on up until today, but more on that further down...

Yeah, I don't know how his engine is designed...I'm just going off of what I know with my car, which obviously is completely different.

Oh wait, that's right...I don't need to take off my valve covers completely to get to the spark plugs...they are set deep in the valve cover general area, but I forgot the valve cover comes out around the spark plugs...though, to get the valve covers off, the spark plugs and ignition coils do need to come off, and that's when you can see if your valve cover gaskets are leaking or not.

I figured that much since my spark plugs are within reach, though they are set pretty deep.

Just out curiosity, is this car supercharged by chance?

That MX6? I don't think so, it just has a funky intake, as far as I know. My Millenia isn't either.

Anyways, I removed the MAF, intake hose, and air cleaner box... Cleaned each. Didn't really make a difference. After that, I went to Advance Auto to pick up a new air filter and then headed back home. This is where the fun starts. On my home, it shut off again... about 6 different times, the final time for good. Not only that, the check engine light is now blinking, which, I'm pretty sure isn't a good thing. All this while it was storming and I was in the middle of nowhere, the first time. I got started back up shortly after. Crawled along, trying to make it home. Just as I reached the top of the hill by my house, it shut off for the final time and wouldn't restart. Coasted down into the valley and tried to keep enough speed to get to my driveway after turning sharply onto the dirt road. Without power steering, it was a task, for sure. It now sits at the end of my driveway. Back to how it was running... Any time I would hold a gear, it would automatically shut off, which was the cause for half of the times it did so. It must be in "limp" mode. Really, it doesn't seem to run any worse. I think it has to be a one of the oxygen sensors or the MAF sensor. I just need to pull the codes... If I could. But yeah, that was my day... *jumps out his window... lands on porch roof... says "Damn!" and climbs back inside* :P

Dude, that sounds eerily similar to your last drive with the GA. Probably the limping home part, not so much the mechanical part. Well good luck with it, hope you get it fixed soon.

I'm reading up on it on these Mazda forums...I guess 95's for some reason incorporated a lot of OBDII features, but it isn't 100% compliant with OBDII. Supposedly you do have OBDII ports though...very odd. From there on out they were OBDII.

Where? The only ports/plug ins I know of are under the hood and they're certainly not OBDII. If I could find this supposed OBDII port, I could end this wild goose chase as we have an OBDII diagnostic reader. I can't find anything of the sort under the dash. Edited by blackviper8891

Oh Viper... a flashing Check Engine light is not good. A steady light means something should be checked, a flashing light means shut the car down immediately and do not drive it any further. I would call the closest Mazda dealership service department regarding your OBD setup, see if they'd be willing to answer the question of which reader you need and where to plug it in, and is there anything in the owner's manual that could help someone diagnose it for you? Do any of the underhood labels, the emissions label perhaps, say anything about "OBDII certified"? Edited by ocnblu

Obviously.. I was being sarcastic. I made sure to check all the vital fluids and other things before driving it, but I found nothing out of the ordinary and it seemed to be running fine. Either way, I didn't have much of a choice but to limp it home since I was literally in the middle of nowhere with no nearby houses and I had no service on my cell phone. Not to mention it was storming and I was bring food home. :P

I certainly need to find out about the OBD setup. I'm going to do another lengthy search under the hood and beneath the dashboard for any plug ins.

I believe there should be a port underneath you steering column, or on/under the kick panel to the right of your right foot, or somewhere in that general vicinity.

I'm looking at this, btw...seems to be a lot of confusion on the matter....
