You are in the Mazda Protege
What is this discussion about?
Mazda Protege, Sedan
Oct 20, 2003 (8:08 am)
No check engine light, just pinging under acceleration or uphill driving. With pinging these are the possible causes:
1. Incorrect grade of fuel. The Protege calls for only 87 octane and that is what I use. I buy gas from different stations in the area.
2. Problem with engine control system. Other than the pinging, the car seems to run fine. So my guess is that the car's computer is ok.
3. Fuel injection system faulty. Again, the acceleration of the car seems fine at various speeds.
4. Damaged spark plug wires or plugs. I replaced both recently.
5. EGR vlave not functioning.
6. Vacuum leak. I checked all the vacuum hoses and listened for leaks. Found none.
Considering that the EGR valve's purpose is to recirculate exhaust gases and thereby lower combustion temperatures, any problem with the valve could lead to higher combustion chamber temps and therefore pre-ignition or pinging.
My source of information is the Haynes "Mazda 323 & Protege' 1990 thru 1997 Automotive Repair Manual, copyright 1997." I recommend this book or the Mazda Protege Service Manual.
#1813 of 3742 Big Problem
Oct 21, 2003 (8:30 am)
My 1999 ES has 56,000 miles.
But... it SQUEAKS/CREAKS like an old boat when it goes over bumps the first couple of times in cold climate. This started happening after 45,000 miles. Never before.
What is causing this? Shocks or springs?
#1814 of 3742 Noise over bumps
Oct 21, 2003 (10:40 am)
Chikoo, my Protege (1999 ES 43K miles) shares a similar problem with yours.
First I thought that it would likely be due to the worn-out struts, but when I brought the car to a garage, I was told that the noise comes from the two sway bar end links. They would charge me $113.70 for replacing the sway bars, but I decided to delay my decision. I am still not sure what exactly this means: The noise comes from some loose ends or worn-out bushing? Or could some greasing make the noise gone?

I think those are covered under my extended warranty. I will have to get my car to a dealer ASAP.

my '99 es does this over extreme speed bumps. I don't think it's a problem.
#1817 of 3742 Front axle, ball joints, tie rod ends
Oct 24, 2003 (7:18 pm)
I am getting my '95 Protege LX with 163K miles back into "like new" condition (see previous posts).
Over the last few days I have been struggling with the replacement of the right front half shaft and associated suspension/steering parts. Got all the parts at O'Reillys and was almost near the end when I hit a stopper. The '95, and I am sure later versions, has a right front half shaft in two parts with a bracket and bearing in the middle. I could not separate the two shafts, completely frozen. It looked like an easy job for a specialized puller or spreader, but I sure couldn't find one at the auto parts stores. So considering that I was doing this on the ground with jack stands and couldn't disconnect the bracket due to lack of space, I conceded defeat. But I did replace the tie rod ends on both sides as the grease boots were cracked open. I also noticed that the ball joints on both sides also had cracked open grease boots. This was likely the cause of a popping type sound I was having as I came to a stop while driving.
So I call a nearby shop and set up an appointment. They look at the car and tell me that the boots are fine and they couldn't hear any clicking noise. I disregard their ignorance( I have been listening to the clicking every morning on left turns for the last 100K miles)and tell them to replace the half shaft. They check the play on the ball joints and say they are still ok. I tell them to look closer at the cracked boots and then replace them (A sure sign of bad customer service is when they argue with you over what you want done). So they finally do the work. The bill, $466. 2 hours labor at $86 per hour and aftermarket parts marked up 50% over what I paid a day earlier at O'Reillys, but at least it's done.
Tomorrow I have the alignment checked (thankfully for free) and then the old Protege will be ready for the next half of its life.

A friend of mine has a 97 Protege, 1.5L, 5 spd., with 67K miles. She told me the other day that her CEL came on. I had the codes pulled with my scanner, and got only one: P0505. Since I did not have the table with me at the time, I asked her if she had tightened the gas cap. She said that she never makes it 'click', so I said '...that's it...'. However, when I looked P0505 up on the web later that day, I found "Idle System Control Malfunction". I called her, and asked her if the car had ever stalled or idled erratically after the CEL had come on. She said that the car has not done anything different - No problems she can tell. Can a loose gas cap trigger a somewhat unrelated OBDII code?

If it comes back again, then it is a repeatable problem.
#1820 of 3742 Gave myself a scare yesterday.

I put the strut tower brace into my '99LX (yes, I know, it's not really made for the 1.6L engine bay, but it definitely helps lateral motions), and it comes pretty close to the top of the engine.
If I accelerate hard enough at low RPMs, especially in reverse, I can hear the strut bar being hit by the engine. Well, an air hose shook off near the top of the engine (highest point, towards the driver side and facing the rear). Apparently, this hose leads to a pressure sensor that helps the ECM decide how to run the engine, because idle got low and unsteady. Power still seemed OK.
I thought the MAS unit I'd had put in as part of a recall was failing like the original faulty part, but plugging this hose back on fixed everything (hey, saved myself the diagnostic fee!). I put a nylon cable tie on it to help keep it on (either the metal clamp wasn't installed or it got shaken off), so I don't do this to myself again.
And yes, I did raise the strut tower brace with a set of washers (thanks to a suggestion I got here on one of the Edmunds Protege boards). I don't dare raise it any more as I'm afraid I'd run out of thread on the studs at each strut tower.
#1821 of 3742 Ignition Coil Recall
Oct 27, 2003 (2:43 pm)
I had the coil fail on me (2000 Protege ES) a month ago and my mechanic changed it and said that "...Mazda almost had a recall on this issue...". Now I read in the forum some say that there actually IS a recall on the coil.
Can anybody give me some details on it? Recal#, date issued and so on, please?
I think it might be time to go and get some money back from the beforementioned mechanic.
btw. yesterday my cat converter had the check enine light come (which makes sence with the faulty coil...)
