#27 of 36 Idle's at 200 to Zero by MazdaChick Jan 24, 2009 (8:02 pm)
I own a Mazda Protege 2000 just purchased in August, I am having some idling issues, was only idling at 200 and was fine at first I have now replaced, plugs and wires twice, and O2 sensor, the mechanic seems to think it could be my cadillac converter, once they replaced the O2 sensor it started to run worse down to 0rpm all my lights would come on (check engine, my oil light as if the car stalled) and then it will jump up to 2000rpm and jumps my car forward. I have had my car for 5 months and it has been back and forth to the shop since any advice? Replies to this message: autonomous (Jan 26, 2009 1:22 pm)

Replying to: MazdaChick (Jan 24, 2009 8:02 pm) Have you had your EGR (Exhaust Gas Release) valve checked? If dirty, it can create a bucking sensation with wild jumps in the RPM.   This is a known issues with Proteges. Are you dealing with a Mazda garage?   p.s. The "cadillac converter" is actually a catalytic converter, but cadillac converter has an interesting ring to it.

Look for air leaks on the intake side, particularly in the accordian-like hose between the air-cleaner and the intake manifold. Any air leaks at all will screw up idle, while impact while driving will be less noticable.

Replying to: mazdaman10 (Sep 09, 2008 11:51 pm) Your Problem is with your alternator. It's been damaged, or is just worn out. Try using a volt meter w/ the engine running at about 2500 rpm. If it's below 13.6 volts, then you're alternator's bad. Change it out by removing the Catalytic Converter, and pulling it out that way, if your Protege' has AC. If it does not, simply unbolt the cruise control, and if needed, the module next to it, and pull your alternator out the top. If your alternator is not the problem, check your air filter, and the coil air intake hose for breaks or leaks. An error in the fuel/air mixture could make the engine "gasp". Also, check and make sure your battery is still good, and if your connection posts and clamps are clear of corrosion. If you have any further problems after trying these steps, visit your local Auto Zone, or contact me at protege-info.webs.com ...   PS: Try to keep the engine from backfiring. Don't let the engine putter down, let of the gas, and floor it again in an attempt to get it going, because each time you do, the engine will backfire once or twice.

Replying to: codon_shifter (Jun 06, 2008 4:38 pm) This sounds like a vacuum problem. Or another electrical meltdown. Assuming you have power steering, the pump could be draining the engine of power. Not during normal speeds, because the engine is working hard. Check your battery for corossion, and get it replaced or the connections cleaned. If this doesn't work, check to see if either of your belts are loose. If so, tighten them up so about 2 pounds of pressure will bend it in about a half inch. If this still isn't the problem, press the clutch when you make these sharp turns, and give the engine some gas. Just enough to keep it from the chance of further damage until you can figure out what your problem is. Remember, your steering is powered by the engine, so check to make sure it's getting enough air. Giving the engine some gas in those tight turns should solve your problem.

Replying to: good_boy (Mar 06, 2006 8:20 am) A common thing for a protege' to do is to vibrate when in gear. The car's engine was designed with only 92 hp, so the engineers had to put all of it to the ground. The protege' has a strong get up and go, so it will tend to do that. Check under the hood while someone else is in the drivers seat, and listen. Move around to see if you can figure out where the sound is coming from. It is most likely just a loose part, or a piece of road debris.

Replying to: 95mazda1 (Mar 07, 2007 7:18 pm) I just recovered from this problem today. Your problem is your alternator. It has been damaged, and needs to be replaced. It's not putting out enough juice to power all your appliances in the car, so cuts corners on important electronics like headlights, and speedometer, and the airbag light will flash. Be very careful, as a flashing airbag light means there is not enough power to deploy them in case of a crash. Replace your alternator, by removing your catalytic converter, if you have AC. If not, undo your cruise control, and the other module below it, and pull your alternator out the top. There is no other way. Also, make sure your battery is good, and your connection post and clamps are free of corrosion and rust. Hope this helps.   PS: Your radio died first because it takes the most power, besides the engine and headlights. Replies to this message: giacomod (Apr 17, 2009 3:55 pm)

Replying to: zoom60 (Jun 04, 2008 1:56 pm) There is nothing wrong with your car that I know of. It's running high at first to heat up, so it doesn't die. The engine is designed to idle at 900rpm, so if it drops to that after a few when cold, everything is normal.
