Question about 2001 Mazda 626

2001 automatic Mazda 626 6 cylinder won't accelerate properly, won't go past 60 kph when going up a hill or past 90 kph when driving normally. We put the engine analyzer on it and got a whole bunch of

My husband says he checked the hoses and plugs and everything is ok, the engine will rev up properly when he controls it from the engine, but I can barely get any power from it when I'm driving it. He thinks it's the fuel rail and I'm really hoping he can fix it. Thanks for all your help.

SOURCE: 1998 mazda 626 check engine light flashing

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. A technician will have to perform further testing to pinpoint cause and the proper repair. When the light starts flashing the computer is telling you to have the vehicle looked at now before other problems happen.

SOURCE: Mazda 626 2.2L Turbo 1989 - Alternator - Fuel Pump

Hi am just up the road on the SSC, it is easier to remove the alternator from underneath the vehicle & if you look under the carpet under the rear seat there is a plate which gives you access to the fuel pump cover in the tank. The pump can be accessed from there. If you want the workshop Manuals I have just uploaded them.
You can download the GD 626 Workshop manual & the Turbo supplement by going to the 626.net site.
Cheers

SOURCE: When accelerating the engine seems to stutter.

Try unplugging your Mass Air Flow Sensor (MAFS) - you'll find it on top of the metal body immediately after the air filter. I went through an 18 month ordeal - replaced fuel filter, fuel pump, dropped fuel tank and cleaned it, ran 55 gallons of fuel injector cleaner through the system - nothing! After reading some blogs on this car/engine, gave the MAFS unplug trick a try. The car instantly corrected itself (when you unplug this sensor, the engine control module reverts to factory default, allows sufficient fuel into the engine for unitterupted performance.) However, if this corrects your problem, it's only a temporary fix. Run it about 3 days - it you notice soot in the tailpipe, the factory default is running too rich. Replace the MAFS.
