#1340 of 1420 High Rev on idle on hot days!
Apr 28, 2009 (5:09 am)
I am experimenting problem with my Mazda Protege 5 2002 with 165000km The problem first occurs at the end of last summer. When I get stock in traffic on hot day (30 & +) for more than 10 minutes, the idle is drastically increasing, regular idle RPM is 900 but it slowly increase 1500, 1800, 2500, 3000, 3500, etc....It gets higher everytime I move of a couple of feets. Suddenly, when the traffic jam is over and I go at a regular speed (80km/h) for 5 minutes, it stabilize & the idle come back to his regular speed.
I wonder if the problem can be the EGR Valve, I didn't brought the car to the garage for this problem because it just come back with new shock in front. The garage change my radiator after I crash my front in december 2007. I'm pointing at the new radiator to not be as efficient at the original one since it needs constant flow of air to refresh. Also I'm planning to change the timing belt but I don't see how it can make a difference.
Can you give me some track to look at plz??

I agree with you that it sounds more like the radiator than the EGR valve. When I had my EGR valve issue, it felt like my 2002 P5 was gasping for air and the revs shot up from the idle to a much higher number (like 2500 rpm). Once the problem started the car was very difficult to drive, so I needed to have the EGR taken care of quickly. The fact that your car has had this problem for nearly a year and occurs during hot periods seems to point to the radiator or some related item (like a hose). I would check around the engine to check the condition of the hoses. If they appear fine, return to the garage responsible for installing the radiator and ask them to check it out again and correct the problem (hopefully, at no or limited charge to you). If they don't agree, you may have to go elsewhere.
#1342 of 1420 Fuse Box -- Cracked Fuse and Missing Fuse -- Diagram Available?
May 23, 2009 (2:39 pm)
- 2002 Protege5 -
Just happened to open the main fuse box under the hood and found one of the fuse's plastic housing is broken and another fuse is completely missing! I've been on the hunt for a fuse box diagram and haven't been able to find a complete one. We don't have the original owner's manual however I found one online but it only outlines half the fuses in the fuse box! Ha!
Looking at page one (09-21-01) of the PDF above: The fuse with the cracked plastic housing is directly above #3 and on the right of the two. The missing fuse is the 4th down on the right row of single fuses (to the left of the double fuse row).
Any help is greatly appreciated.
I'm hoping someone here can lend a hand in identifying what these two fuses are for.

If you look under the fuse box lid, printed on the top is the fuse schematic. Depending on your options, there may be empty slots.

Anyone know anything about engine surges when more than one electrical item (such as wipers, lights and blower) is running? I just purchased this Protege5 Hatch with 102,000 miles, recently had to replace the thermostat, timing belt is next just because there were no maintenance records on this vehicle when I bought it, so it's time for the belt I'd say. But the surging whenever more than one electrical item is being run at the same time is the weirdest thing I've ever experienced. It feels like it's either changing gears up and down or just surging forward every few seconds, then it lets off and surges again, etc. If anyone has any ideas, please post. I'd like to know what I'm dealing with before I take it in for repair. Thanks!

surging whenever more than one electrical item is being run at the same time
So, the surging does not happen at other times?
How does the tachometer react during the surge? Higher rev range?

Hi, my mp5 2002 150,000km is doing exactly the same as yours did last April. Could you please tell me how it did get resolve? My Mazda dealer just called me today, June 29th, to tell me they don't know what is going on. I had the EGR valve replace 1 year ago, but since the Check Engine light doesn't come on, they say it is not the EGR valve this time.
Thanks for your time.

Well, I've been avoidind the problem by not getting jammed in traffic when it's more than 25celcius outside... I will bring the car to the garage in a couple of weeks to change the timing belt and i will let know my garagist the problem. Hopefully, he is going to fix the problem (which I doubt) or I will keep avoiding heat trap. Anyway, since April, it didn't really occur again, but I wasn't jam in traffic for more than 15-20 minutes on hot days. I'll give you an update after my visit for the timing belt. In the meanwhile if someone find a solution, let me know.
