driving and all the sudden the rpm's went all the way into the red. Now when I turn the car on it does the same thing
 
Could be a few things ... When my EGR valve failed, it caused the car to rev wildly as if it was gasping for air. The EGR valve is part of the emissions control system. You may want to have a diagnostic test done to determine the exact problem.

#40 of 50 Protege Idle Air Control Valve Specs by matt1964

Hello,
I've similar idling problems to many others; mine is a '96 with 100,000. Mechanic said "Idle air control valve", and also the torn intake air hose (bad engine mounts let the engine shift and it has pulled this hose to pieces). Ordered the hose on ebay; meanwhile, it's taped. Replaced the IAC valve (ebay, also). No change: rough, variable RPM while in gear and stopped, okay when driving or in P or N. Question: manual says resistance on the IAC valve terminals ranges from 1070-1230 ohms; both the old and the ebay replacement measure 880 ohms. Curious that they're both 880 (unless, of course, they're both 100,000 miles old!). Is the manual accurate?
Thanks, Matt

Yes, that does sound a bit high to me.
Could be a bunch of things: cold, not driven frequently, throttle body/fuel system dirty ...
My 2002 starts at 1100 before dropping to 800..
 
Next time you bring it to a garage, mention it to your mechanic to hear what he says.

#43 of 50 I have similar problems, help! by diyking

I purchased my 2000 Protege 1.8 ES with 135K on it, and it had a low idle and eventually would stall under moderate to hard acceleration. I took it to Autozone for the code readout and got "system too lean", and "cyl. 4 misfire". I read some forums, and the car now had a brand new EGR valve, brand new ignition coils, which didn't help at all. I just got done installing a new intake manifold gasket, and now the car idles very high (between 2500 and 3500 RPM), and the hesitation under acceleration has not been cured. HELP!

Sounds like you might need to bite the bullet and bring it into a Mazda garage to get the diagnostic and their suggested cure. Otherwise, you may end up spending even more money replacing parts that are not the problem. Good luck!

Yes, that's the point I'm at. No sense in throwing darts, as they say, just finding that out the hard way. As for the high idle, I just installed the accelerator cable incorrectly, quick fix. My biggest fear is the head gasket, I've changed one in an '83 beamer but it wasn't this modern. No signs of that though, does not burn antifreeze or oil. Good thing the Mazda dealership is about 5 minutes down the road

i've heard sooo many people have a problem with bad idle 200-1000 rpms!this is a nightmare on proteges but what ive done is give you my checklist right before you go to mazda. remember keep it simple!
 1996 mazda protege
1. replace your air filter if bad
2. get some cfc maf cleaner only clean maf sensor (located in top of air filter cover 15 shots of spray through the screen side only and wait 15min til dry)
3.remove air hose between maf sensor and throttle body in the accordian section check for rips any cracks replace remember when replacing air filter to remove this hose or you will crack it.(this also can be caused by a bad motor mount)
4.egr valve located on backside of intake remove intake hose, 2 12mm bolts and label the two vacuum hoses on egr. with brakekleen spray into 2 holes with carbon build up clean shaft well oil then press diaphram up and put your finger on vacuum hole if diaphram doesn't hold and move freely replace.
5.check catalytic converter basically go to tail pipe and check for good flow of exhaust
6. battery /alternator clean teminals, load test battery,with multimeter in dc check voltage you should be getting atleast 13.8 volts idle
7. Iac sensor i leave this for last because its pricey so far my check list has cost you a bottle of cfc maf cleaner and your time at this point head to mazda
hope this helps

If you own a Protege, just call a Mazda dealership service shop and give them the VIN. They can look it up for you. We have recall info on our site, and NHTSA has it too, but you're stuck looking year-by-year.
