i was wondering if your latest fix has worked...i also have a mazda 626, 1999 lx 4 cylinder....i started having problems late last year, very similar to yours.....when i'm sitting at a light, the pressure drops hard and fast..when i give it gas, it sputters and doesn't want to go, which is even more noticeable when the air/heat/fan is on, i actually have to turn it off in order to go!! in december, i took it in for a diagnostic, but nothing really came up as i'd just replaced my battery weeks before, except one bad spark plug and the wire..my mechanic suggested i use a higher end wire, but i chose another as they were around $30 cheaper....the car was back to normal after that until about two weeks ago, when the check engine light started coming on again when i give it gas and it's shuttering again, so back to everything that happened last year.....everyone i've spoken to thinks it is the oxygen censors, though one person thinks it could be the fuel injectors.....the O2 censors are around $170 just for the parts, so i don't want to waste the money if this isn't it......sooo, just wondering if your latest worked as we seem to be in the same boat........if not, possibly the O2 censors or fuel injectors, from what has been suggested to me............btw, i've even taken my car in to auto zone type places when the check engine light is blinking and nothing shows up, to which i'm told that the computer isn't holding any info.......

I'm going to buy stock in companies that make 02 sensors.
No one is properly diagnosing this car. No codes, REALLY? That's very strang. Oh well, -- Why don't you dose it with a VERY strong injector cleaner, like from Swepco or BGK44, and then after running that for a while have someone read your air/fuel mixture---would be great if you could get on a dyno but I know that's expensive.
Being an intermittent problem, it could be injectors. I don't understand why we have no codes. Remember, a code-reading machine is only as good as the operator using it.

yep, no codes!! of course, this was done at an auto zone..i've made an appointment for saturday to get a diagnostic done on it, hopefully something will show up since i have not changed the battery this time! my neighbor suggested an injector cleaner, which i did when the problem first started, as well as when this originally began back in december, and no luck....it is getting worse each day..the check engine light came on twice coming to work this morning....if i slow down or stop completely, it has trouble getting gas when i start to go again.....and again, it is worse when the air is on, and i'm in georgia, hard to go without air this time of year!!! i'm hoping that nothing shows at auto zone because their machines are basic, but my gut tells me i may end up with a new car soon! thanks for your help!

Well sometimes something has to fail to pin it down.
#1719 of 2547 2002 626 Idle Question and Strange Comment
Jun 10, 2005 (3:32 am)
My girlfriend bought a 2002 626 in 2003, it's got an automatic transmission, lately (as in the starting of summer) when the A\C is on, primarily anytime the car is stopped, i.e. stop light, stop sign etc. it almost feels like the car is killing out, but in very, very, small bursts! I turn the A\C off and it stops instantly, and when I start to accelerate, the instant I engage the gas pedal, there's almost the same sputtering feeling before it starts to accelerate, Id like to catch this problem now, I hate working on these japanese cars, and in past experience what would be a common sense fixing problem, turns into stuff you couldn't have even perceived in the end, any ideas? also anytime it rains or snows(i live in utah) the passenger side floor turns into a damn!!! sometimes so bad we have to wetvac it! it's very irritating, and also the hazards and\or left-right turn signal will activate itself and will not turn off unless I pull out the fuse, the other night the cops banged on my door at 3:45a.m. seeing my car in the drive way shut off, signaling right!!! this also happens only when it has been raining or snowing!! any ideas on this. It's just pathetic, it's been a decent car, but decent really dosent cut it in my book anymore! Thanks

well i changed the cadilac converter the other night and that wasn't it either,i'm glad i changed it anyways some idiot who had the car before me clean it out so it made the car sound loud,anyways i did notice that my fresh air intake hose was really broke ,and to much air to the motor can cause it to not run all that great,so i ordered one of those it's not but 15.00 dollars,i tryed all the really great fuel injector cleaner,bc i thought that would mabye clean them out ,it's not running any better,i just hope and pray it the air intake hose and not the fuel injectors

i see that you and i are having pretty much the exact same problem, except for the latter part of your messgae! i have an appt tomorrow to get mine changed checked out, via $65 diagnostic test! i'll let the board know what i find out, hoping it's not expensive! from what i've read, the 626 stopped being a japanese made car around 1994; they're made by ford now, which is an acronym for 'fix or repair daily!' i'll keep you posted on what the problem is!
#1722 of 2547 1998 626 5spd 83K Miles - sucking sound coming from engine
Jun 11, 2005 (11:29 am)
I never noticed the problem since I bought the vehicle a year ago, but I just got an oil change and the mechanic told me the engine was making a sucking sound that might indicate a cracked intake manifold. (This place doesn't fix that sort of thing, though) I opened the hood and heard it for myself, and it certainly isn't a healthy sound to me.
From what I've read on this board, this seems to make sense, since this car sometimes stalls when idling, but only when the engine's hot.
When it comes to cars I know very little. What I need to know: Is this a serious problem; should I get it fixed immediately? Also, what should I be expecting to pay for this repair? (Feel free to throw out estimates based on total guesses of what the problem might be.)
So far this car has performed wonderfully, save for a radiator leak over the winter and a strange clicking sound coming from the front wheels when I make a really tight turn (my last car, a mazda 323 did that as well, and it always worried me, but never seemed to be a problem).

It's rather odd for an INTAKE manifold to crack....exhaust manifolds are much more likely to do so.
If you have a vacuum leak, sure, that's serious---you could burn your valves by screwing up your fuel mixture and driving your little engine computer crazy. But most vacuum leaks aren't that hard to fix unless the intake manifold is WARPED...and even then you can often take them off and have them machined flat again.

i got my car looked at today and wanted to let you know what i found out....he ran the diagnostic, i'm not positive how to explain this, but basically, he said that the problem had not been occurring to long, so the problem had not been set officially in the system that the test reads.....the important part is this: one of the spark plugs had a crack in it and the spark plug wires were put on a little backwards...he said both of these things would cause the problems i'm having....he was not thrilled with the brand of wires that was put on it, he prefers a brand that of course, i can't remember! he did say that the oxygen censor shouldn't cause the problems that i'm having....basically, it's fine now, told me to watch it...only $100, it could have been worse! good luck! maybe you should change your plugs!
