#2913 of 3742 Stalling when warming up
May 01, 2006 (9:33 am)
I have a mazda protege 1993 SE. I have a similar problem... When I start the car (in cold temp), it runs perfectly. When it almost reaches its optimal temp, and I drive in city (lights/traffic), and shift 1/2/3 or just step on the gas while stopped, the engine stumbles too. This can last for 10 minutes and disapears. But if I do highway (from cold engine to full temp) I feel nothing. Again, the difference in my case is that I can always start the car when its fully heated. The problem seems to be gone in summer (I'm from Quebec), but the stumbling came back when I drove through a big puddle of water even with a hot engine. Can the car be sensitive to humidity? I found out it might be the coolant sensor, just like you guys mention, but in my case, the temp gage doesn't show abnormal temps. Engine light doesn't go on either.

If it seems sensitive to humidity, or when it's raining out, I would check the ignition wires and/or coil first.

I forgot to mention that when I had that problem with the ATX ("O/D off" blinking light and tranny slipping into 3rd gear on the highway ) that the air hose was cracked, so air was leaking through. I have since repaired it and changed the TPS, of course, and everything is running fine, but I'm wondering if the cracked air hose wasn't adding to the problem, or if it maybe was the original cause?
#2916 of 3742 PCM and A/C compressor
May 12, 2006 (12:28 pm)
Hello all, recently brought my 99 ES 1.8L to the dealer to check out the A/C since my compressor would not kick in. I was told it was the PCM not sending a ground to the compressor. I'm obviously not going to replace the PCM for $1200 for this but I'm hoping someone can tell me they were diagnosed with this same problem and found an alternate solution. Thanks for any help..

You can always try a used PCM.
Where I live, the auto-wreckers sell PCM's for
Protege for about $100. They come with a 30 - 90 day
guarantee. I have replaced used electronics and they
have worked now for years.
I'm not familiar with the part, and don't know if you
can change it yourself or not.
Just call up every wrecker you can until you find one.
#2918 of 3742 Raspy Exhaust Note in 1998 Mazda Protege
May 18, 2006 (2:08 pm)
After having my motor mounts replaced, my transmission failed and needed to be serviced. Since receiving my car from the mechanic, I have noticed that the exhaust note has become very raspy. Moreover, after coming to a complete stop, my car will hesitate breifly when I press the gas. I read on the net that when the transmission is removed for service, that the transmission mounts should be replaced. Is it at all possible that the problems I'm experiencing are related to the transmission mounts?

Does anyone know the technical explanation of the o/d button?
#2920 of 3742 99 Mazda protege - ATX issue
May 19, 2006 (7:42 pm)
I have a 99 Protege, with 59K on it.
Recently, it has started blinking the O/D light once in a while, which goes away if i turn off the engine and turn back on. Shifts are somewhat rough. I can also hear some sort of a noise when shifting in lower gears. Hasnt given any problems on the highway yet - works absolutely fine when running at speeds.
Having read all messages rgding auto-trannies on proteges, can someone give me a couple of options to diagnose issues for the autotransmission?

Does anyone know how to safely clean the EGR valve on a 98 Protege?
I was thinking about adding "SeaFoam", but I would prefer only to apply it to the gas tank and engine oil.

Here's a few questions:
1)Is the check engine light on at all?
2)Have you scanned the engine for a code?
3)When the "O/D Off" light is blinking, can you
get into overdrive, or does it stay in 3rd or 2nd gear?
4)Is the air hose in good shape- no cracks, or air leaking out?
Okay, just to give you more info, go to this site:
Then go into page 15, that's DTC TABLE[FS]...01-02B-15
If you look across the headings, DTC NO.,Condition,MIL,
then "O/D off indicator light", follow that down to
P0122 TP circuit low input, and P0123 TP circuit high
input, you notice that those both show Flashing, right?
I was informed by a mechanic that the computer does this
blinking thing just as a safety mode, possibly to prevent
bigger damage, and it makes the driver stop the car.
Your car may possibly be in the early stages.
By the way, I can't take any credit for that other site I
mentioned, since someone else mentioned it here first.
