Question about Mazda 626

6 Answers

I have 1992 Mazda 626 dx w/2.2L 4cyl engine. The check engine light came on after i replaced the rack and pinion. I replaced all the vacuum lines, Sprayed the butterfly in the throttle body with carb cleaner. The engine stalles when you let go of the throttle quickley, runs rough when accelerating, puts out black exhaust on the driveway. Replaced the distibutor cap and rotor,cleaned the plugs that have a 1000 miles on them. What should i do next,how do i pull a code from the computer?

    I had the negative cable off the entire time i replaced the rack and pinion

  • wklemp Dec 20, 2008

    i did take the negative cable for 2 minutes. The car ran fine before i r/r the rack and pinion.

  • wklemp Dec 20, 2008

    The fuel filter was replaced shortly before i r/r the rack and pinion. Is there a way to find a code thru the computer? I sprayed the butterfly with carb cleaner when i took air hose off the throttle body. When i had the air flow hose off, i reconnected the plug and saw the air flow working.

    I am trying to find out how to pull a problem code off my 1992 mazda 626 2.2l engine. When i just slightly touch the throttle it seems to want to stall. At idle it is ok, rev the engine and it feels like it misses. What causes the black exhaust (not smoke) to be released? Do i have a vacuum situation,a fuel mix,or air flow problem?

  • wklemp Dec 24, 2008

    I could not find my obd connector under the dash but about.com showed me how to pull a code off of my cel. This code flashed 8 times, showing a air flow meter problem, what can be done next?

  • wklemp Dec 24, 2008

    I have removed all the spark plugs and they all were black, before i did that i remove each plug wire while it was running and all had spark.

  • wklemp Dec 27, 2008

    The o2 sensor is 2 months old. Do you think when i first sprayed the butterfly with carb cleaner i could have done something to the idle control?



  • wklemp Dec 28, 2008

    I will attempt to clean the iac and let you know how i made out. Thank you and have a Happy New Year

  • wklemp Jan 05, 2009

    after i cleaned the idle control valve the engine revs high and low now. I took it for a test run but it is still acting up. I will attempt to remove the icv and see if it is working.

  • wklemp Jan 17, 2009

    I have not worked on the car in a week, after i took apart the idle control and cleaned it, it ran at a high/low idle. Do i need to take it apart again or is there another solution.? Do you know if there is a kit for rebuilding it since a new one is too expensive? Thank you.

Do u have a check engine light on? if not u will get no codes, next check the fuel pressure, make sure it is no more than 40-44 PSI, the stall issue can be caused by a couple of things other than above, one is a MAF, the other is the TPS, on this system niether will set a code or turn on the check engine light, the computer control on this car is very primitive, u will need to check the output or signal return values for both sensors.

Hi and welcome to FixYa,

Offhand, when you removed the negative of the battery, you have done a reset on the engine management computer. Having done so, the computer would have to re-learn which could have been done driving around for at least 30 minutes.
A couple of ideas to explore:

  • The black exhaust is indicative, fuel mix not burned completely. But what would be more telling would be how does the ends of the sparkplugs look like, whitish, brown or black?
  • are all there sparks at all the plus;
  • try removing one at a time and determine if there is spark at each;
  • if there is vacuum leak, confirm by spraying with starter fuel or injector fuel any junction after the air filter casing's base plate all the way to the intake manifold/head junction;
  • if it is an air leak try spraying the same around the air filter except the actual air port.
Good luck and Thank you for using FixYa. Happy Holidays.

    Hi again,

    Appreciate the update and developments. To answer your specific queries:


    • black exhaust - rich fuel mix, too much fuel, little air;

    • vacuum situation - could only be a leak but would be indicated by high idle;

    • fuel mix - computer does the mixing, fuel by injectors, air by the IAC

    • air flow problem - possibly restricted, dirty air filter?

    • spark plugs...black - rich fuel mix, too much fuel, little air;

    • each plug...had spark - good sign, limits problem to air/fuel mix, the computer is good.
    Others to check/clean/replace would be the Idle Control Valve (IAC) valve assembly and the O2 sensors.

    Cheers.

    When you "sprayed the
    butterfly with carb cleaner
    ", the gunk, dirt and dried up fuel residue would loosen and flow with the cleaner. If the engine was running when you did this, then that would have been drawn into the combustion chamber. But if when you sprayed the engine was not running and was not started immediately after, that mix of cleaner gunk, dirt and dried up fuel residue would pool somewhere and dry up. It could be at the idle control / IAC.

  1. Ensure that the ignition switch is in the OFF position.
  2. Attach an OBD II compliant scan tool to the data link connector-2, located beneath the drivers side of the dash panel, as instructed by the tool manufacturers directions.
  3. Follow the manufacturers instructions for initializing the scan tool and select the Clear Codes function.
  4. After clearing the code, perform the code retrieval procedure again to ensure there are no remaining or newly set codes present.
Good luck...

    black smoke means to much fuel going in to engine

  • david bridges Dec 22, 2008

    1. If you have black smoke coming out of exhaust that means that the engine runing rich or to much gas entering engine possible fuel pressure regulator not working properly, 2. injuctors staying open and dumping to much fuel

1992 mazda 626 hesitates on acceleration what's

91 626 4cyl non turbo will just shut off at stop when engine warm had code 9 change both temp sensors convertor plugs fire when it dies and smell like fuel now have code 17 any ideas


Code 17 is telling you that computer is not seeing Oxygen sensor changing like it should indicating rich or lean engine running condion. Since you are saying smell like fuel, I would guess at too rich. Is your fuel pressure ok. Pressure should be 27-33 psi with vacuum applied to pressure regulator and 34-40 with no vacuum applied. Also disconnect the vacuum line at the pressure regulator with engine running and check to make sure no fuel is present. Older pressure regulator diaphrams will often rupture which will allow liquid gasoline to be drawn directly into the intake manifold via that vacuum line. This could cause stalling and code 17 as well.

Power steering fluid leak, 1992 dodge stealth


If the line from the power steering pump to the rack and pinion is leaking, replace it.

If the rack and pinion is leaking replace it.

If the power steering pump itself is leaking, then replace it.

Which section is leaking?

1999 mazda 626 4cyl runs rough at idle , engine dies at idle. check engine light on fault code 171 looked for vacum leak none found. replaced MAF sessor no help. any ideas


You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.

Im trying to replace the alternator on a 1999 Mazda 626


Yes, I experienced the same thing with mine... you have to losen the 2 motor mounts on that side and lift the motor up about 3 ". I worked at a garage so I had access to an engine hoist. Try using a jack from underneath. Nice engineering from Mazda!!!

Mazda 626 turbo 1990 power steering cuts out intermittently. Any suggestions? How do you flush and renew power steering fluid?


is your pump belt slipping?  To change the oil you need to remove a hose, drain the fluid and replenish.  However, I have a feeling that you need anew pump or your rack and pinion is binding.  And these are items that need replacement.

This is simple repair if cleaning it doesnt work replace it but if your unsure and want to get a for sure diagnostic you must go to a shop that can diagnose your problem checkers auto parts usually will run OBDII diagnostic free but not sure about OBDI also you can pick up your own diagnostic scanner at local autoparts store or follow troubleshooting guide in your repair manual.
