Question about 2003 Mazda Protege
I own a 2003 Mazdaspeed Protege (Turbo) and my car is acting really wierd. It has a rough idle and when I come to a stop, the car wants to stall. The RPM will drop to about 100-200 then bounce to 800-1000. I've done some research and noticed that the EGR is a problem on the MSP (MazdaSpeed Protege) so I replaced it with the updated EGR. It still does the same thing.
I took it to Mazda and they couldn't figure out what the problem was. They wanted more time with the car but at $98/hour and no clue what the problem was, I said no thank you. Mazda told me that they checked the fuel rail but that wasn't the issue.
The idle on my 2003 Mazda Protege started acting strange one day - it kinda surged forward a little bit. Then the RPM would drop and kept wanting to stall out. It stalled out at a stop sign. The check engine light came on. I drove it immediately to my Goodyear mechanic. It ended up being the Idle Air Control Valve. They had to order the part from Mazda which took 3 days to get there. The whole thing cost $700. Runs great now (again).

I have a 1999 protege and it would stall and run rough at idle, also it would hesitate badly when trying to accelerate. I thought it was the egr - it turns out it is the snorkel (air hose). IThe rubber had hardened and cracked, once replaced the car ran perfectly.

For everyone who is having this problem, I am not sure but hope that it is the same problem I had with my 2003 Mazda Protege, I found out and replaced the intake hose that goes to the filter and it solved my problem, yahoo. Cost $55.00 dealer, online $34.00.
I was frustrated for 2 weeks not knowing what the heck was wrong with my car after I had it at the Mazda service department for an oil smell which my husband fixed by tightening the screws. Apparently the mechanic leaned on the hose and broke it, they said he did not remove anything the second time I was there, but the first time they said he removed the valve cover and saw the the gasket needed to be replaced.
Do not take it back until you look at the hose first, or they will try and tell you it is the idle gasket, or the idle piece that cost about 485.00 to replace.
This is common with most dealers, and or mechanic departments, they know what is actually wrong with the car, and they will fix that problem, and they will tell you it was something else and charge you an arm and a leg.
They told me that my car was old and things ware out, bull dinky, I have an 88 Honda Accord in my back yard, and the hose is in great shape.
I called Mazda Corporation and told them all about my experience with the Mazda Service department, and they are sending me a 60.00 voucher for any repairs in the future to use at any Mazda Service Department.
I love my Mazda Protege, it is paid off and it runs great. I get the oil changed every 3000 miles.

I had this problem too with mine. I would just touch the gas a little while coming to a stop. This is pretty common with this model car. Mazda will reprogram the fuel map to try to fix this. But I never did, I live too far from a "MazdaSpeed" dealership. When my car started misfiring I replaced the coil packs, and it fixed both problems instantly. Now it idles higher.

Replacing the idle control valve would fix the problem.
