Mazda Protege Idling Issues

good_boygood_boy Posts: 1
I bought a 2000 protege (auto) and has only 34 K miles. It runs fine but when I stop on a traffic light or the car is stationary it makes an audible rattling sound. This sound is not their when I am not stationary. Not sure why it's there. Is it typical of Protege's to make such a sound. I also have a 03 Camry and don't hear that. Any info would be much appreciated.

    Hi - welcome.

    You might get some ideas if you go to the Mazda Protege Owners: Problems & Solutions discussion and search for "idling". I turned up quite a few posts about rough idle doing that.

    The Search This Discussion box is on the right just above the first post and just below the last post on the page.

    Meanwhile, I've given this discussion a bit more of a generic name so that others can join in here if they'd like.

    Good luck.

    I was driving my Mazda and 1st the radio turned off. It stalled out in the drive way. I would turn the headlights on and the interior lights it would want to stall mt foot to the floor it would not run. The air bag light is flashing and the speedometer does not work. All this happened after the radio stopped. The car is a 1.5 liter dx with around 104,000 miles on it. I never had much problems with it. If anyone knows or has suggestions what to do they are welcomed. Thank you for you're help.
  • I have a 1997 Mazda Protege and I bought it with 6000 miles on it. I have 189,000 miles on it and never really any problems. The other day I started it went inside to let it warm up about 5 minutes. When I drove it about 1/2 mile it died. It would crank over and start the rpm would go to 3500 then immediately to 1000 and die. I could start it and press on the gas and get it to keep running at 1000rpm, but once I pressed on the gas it would die. My nephew decided it was the fuel pump so we changed it and all the filters. This did not help. There was a few codes that would not clear. I took it in to the local garage for repair. They said that the codes were the mass air flow sensor, eng coolant temp sensor, egr boost solonid, intake air temp, idle system problems. They have had it a week now and do not really know what the problem is. I thought I would post this to see if anyone has any ideas or similar problem. Please help they are baffeled!

    I have a 1990 protege And i'm just woundering what the firing order is for it. I thank it is a 1.8 motor 16 valve fuel injection. problem i'm haveing is it will run and idle but when i give it gas it cuts out. so I changed all the plugs and wires but I don't know the numbers on the distribitor cap so if anyone can help it would be nice.
  • hi! i own a 1999 protege LX,1,6 liter...about a year ago,i fried the original engine,so i replaced it with one that has about now,65.000 miles...everything is fine ,only that lately,while on the road, regarding of the speed(anywhere from 20 to 60!),all of a sudden the gear just kicks into overdrive by itself and the check engine light comes out...i'm afraid that it may affect the transmission in the long run...i've noticed that if i stop,say at the stop light,it kicks back,so could this be related to the breaks? :cry: i have heard that the oxigen sensor might be the reason,anyone knows some details ,or had this problem before,please help!!! thanx guys!

    It could be the EGR valve also. I'd bring it into the shop to have it checked out.

    Does anyone have any info regarding this. The same thing is happening to my 1998 protege.
  • autonomousautonomous Posts: 1,769
    Could you describe the problem exactly?
  • downtubedowntube Posts: 43
    I've done a bit of research on protege idle problems, having bought one a few months ago that idled poorly. Here are the common causes:

    Stuck EGR valve (remove and de-carbonize or replace)
    Vacuum leak (this was my problem. these cars are very sensitive to vacuum leaks)
    Dirty MAF sensor (clean with electrical cleaner spray DO NOT TOUCH WIRES)
    Defective MAF sensor (recall on some model years)
    Carboned Idle Intake Valve (try Seafoam)
    Bad plugs
    Bad plug wires
    Bad coils

    I bought my '98 mazda protege with 50,000 miles on it about a year ago. Right now I am at 60,000 and have been having this same problem for about 6 months. When I am idling, my car will start by making a soft sound. The longer I idle, the louder it gets, with some mild shaking.. So far, I have had my spark plugs replaced, some wiring replaced, and my fuel injectors cleaned.
    The other day my check engine light came on, and the code was for my wiring, and for the coil number 4. It went away when I got the wiring fixed.
    Also my gas mileage has goign downhill lately...
    Any help would be appreciated

    when you cleaned the egr valve, did you just pour the solution into the vacuum? what brand solution did you use? I read online that you just pour into the vacuum and have someone rev the engine, turn off the car, let it sit for a while, then drive it. Is this how you ddi it?>

    Same symptoms I had with my faulty EGR. I had mine replaced by the dealer; pricey solution but it worked.
  • downtubedowntube Posts: 43
    To clean the EGR, you have to remove it. It's a little tight particularly if you have big hands, but there are only two bolts and an electrical connection holding it on. Clean it with brake cleaner. Google for cleaning protege EGR and you'll find a howto somewhere.

    Could be a number of things. Any other symptoms? Have you had regular maintenance performed on the car? Have you had the throttle body cleaned?

    My 2002 Protege5 normally idles between 1000 and 1200 for the first half minute or so and then settles down under a 1000.
  • I have a 1993 Protoge LX 1.8 DOHC with 94k on it. Recently, when I would press the clutch in the revs would kick up like normal, then go way low, about 200. It would either sit there until I gave it gas, or it would correct itself. It even got so low that it would kill the engine, but it would start itself back up. I took it to CarX and they replaced the ignition coil, plugs and wires. I picked it up today. It drove fine until I would slow down and be in first gear and make a sharper turn like into a parking spot. It would rev really low again, but not so low as to die. It seems like it's losing power when I have the wheels turned. I have no idea, but I'm gonna change the air filter tomorrow or sunday. Any help would be appreciated.

    Replacing the air filter will not hurt but I wonder if it's not a dirty throttle body or a mass air flow sensor. Either one will make the car feel as if it's gasping for air. It would also lead to a richer mixture which means higher fuel bills, not a good thing these days.
