#3138 of 3742 Problem with idle?
Apr 18, 2007 (2:49 pm)
I have a 1998 Mazda Protege LX, after I had done a tune-up to it. I notice that on the hood it says the idle speed should be 750 rpm with the car set in park. I can get it to idle at 750rpm but when I put it in drive it idle low below 500rpm and when I turn on the airconditioning it idle around 100rpm. Sometimes it even turns off. If I put it back to the way it was for everything to work I have to set the idle at 1300rpm. What do I have to do to get it to idle at 750rpm like it says to. Thanks Victor

You should not need to set the idle speed screw if the Idle Air Control Valve is working properly. Also, are you adjusting the idle air screw or the throttle adjustment screw? Changing either one can affect more that your idle speed in park. However, since you are already playing with one of those screws, you need to make sure that you follow the proper procedure for adjustment found in the factory service manual. I believe this involves connecting the proper tool to the data link connector and setting it to adjustment mode.
The other option (likely the smart one) is to go see your dealer.

I am planning on purchasing a 99 DX Protege with 70,000 miles which is very clean and original. It is leaking oil from the crankshaft or camshaft seal. The shop of course needs to replace the timing belt and also wants to change the water pump and all the belts and valve cover gasket. The price is $700. Does this sound fair?

I bought a 2000 Protege ES two months ago with 177000 miles on it. Now i might sound crazy for buying a car which has that much mileage on it. But it was a love at first sight when i saw it. It had a full stereo system with dvd monitors and a lot of other bells and rings. The most appealing part was when i test drove the car. the 1.8 l engine coupled with the 5 spd tranny made me feel like i was driving a supercharged car comparing to my 93 civic with auto. And the price was al right. Since the purchase i've been challenging a lot of cars on the road and it shines in it's class. But recently i have noticed the idling problem and i am gonna work on that tomorrow. And by the way plz let me know if anybody recognizes my car (you may be the previous owner) It is a silver 2000 Protege ES with tinted windows, kenwood monitors, magnaflow exhaust, and clarion sub woofers in the trunk.

Price seems a little high, but if the seller is willing to pay and your mechanic feels the car is sound, then go for it.

Mazda wants $850 plus tax and Mazda dealerships here are notorious for being dishonest. For all the labor and parts,(timing belt, water pump and seals, crankshaft and camshaft seals, valve cover gasket, alternator and P/S and A/C belts, antifreeze) the $700 is not outragious in my mind. Again, I'm not paying for the job, so it's a no lose proposition. Afterwoods, all my daughter has to do is drive the car as just about everything is new. Proteges are hard to come by in Florida. Everyone likes them and beats them to death.They either have super high miles cars for sale or low miles and are very expensive on car lots. I guess they have a following.
#3144 of 3742 2003 Mazda Protege Auto Air Controller
May 27, 2007 (9:38 am)
I have a 2003 Auto Air Controller problem where Mazda said with their manual you need to replace it, which is about $700-800. But who knows what might happen next if this doesnt fix it. In the morning when the engine is cold I have to warm it up for aleast 10 minutes to get it moving where the idles for several minutes. But when it is warm the engine runs fine. I have 79K miles and still have a loan on it. Any ideas?

Could you please explain to me where the spark plugs are located? I can not locate them and do not have amaintenance manual.

My wife's 2000 Protege ES (Auto) turned 7 years old last week. With over 86,000 miles on the clock, we got it a new Alternator for it's 7th birthday. The Alternator was completely dead & car was running off battery power.
Is there anything else coming up that I can do preventatively?
