#3240 of 3583 uneven idle speed by karinier Jan 10, 2008 (2:49 pm)
What causes and uneven idle speed from 400 to 1500 or 2000, then back to 400-500. 99 Mazda Protege 1.6 L engine, manual shift. Replies to this message: downtube (Jan 13, 2008 4:43 pm)

Replying to: karinier (Jan 10, 2008 2:49 pm) Uneven idle can have many causes. Protege's are known to have two specific issues that will cause uneven idle:   - Stuck EGR valve - Air or Vacum Leak   Protege EGR valves tend to get clogged with carbon. If they get stuck open, it will result in very poor idle, and reduced fuel economy. If you're mechanically inclined, you can remove it, and either clean it or replace. Do a google search on "HowTo Protege EGR Cleaning".   Vacum leaks will screw up idle. Check all your vacum lines.   The air boot (corrugated hose between the air filter and the intake) tends to crack, allowing air in. This will screw up idle. Remove this boot and check for cracks/tears.   That's a start anyway.
#3242 of 3583 1995 protege is it demon possessed by schesney Jan 14, 2008 (2:14 pm)
My 1995 protege, has suddenly decided it doesn't want to idle, if I pull up to a stop sign or put the brakes on it dies, It is a 5 sp. I am at my wits end, I'm thinking throttle sensor, bad gas, bad fuel pump, help, I'm totally embarrassed to drive it anywhere because of the way it acts. It is bad enough that even when I take off, it surges in 1st gear and I almost have to take off in 2nd. Can anyone give me any kind of help. Also is there anyway besides taking car to dealer to get codes read. Replies to this message: autonomous (Jan 15, 2008 11:22 am)

Sure, there are lots of independent garages that can handle a Mazda protege; you don't need to go to the dealership. You can even try some auto shops which advertize free code reading.
#3244 of 3583 acceleration/deceleration problem by jpu1987 Jan 18, 2008 (2:46 pm)
i own a well maintained 2000 mazda protege dx 1.6L manual transmission, recently the check engine light has come on, its not always on but eventually does come on every time i drive it. when the check engine light comes on the car fails to accelerate smoothly, it seems to either decelerate or be accelerating at full throttle there is no middle ground. this problem often subsides only to return a few minutes later. This is the only vehicle i own, so can someone please help me? Replies to this message: downtube (Jan 19, 2008 7:26 pm)

Replying to: jpu1987 (Jan 18, 2008 2:46 pm) If you're thinking of a DIY repair the first thing you need to know is the code that's causing the CEL. Many auto parts places will extract the code for free 'cause they figure you will buy parts. Get the code and report back here (or one of many online Mazda forums).   Also give a recent history of the car - any changes, have you mainteined it, etc.
#3246 of 3583 Need electrical help by cprdnick Jan 22, 2008 (8:33 am)
Ok, I've volunteered to work on my friends '02 protege. Here is, in the same way I was told what happend, what's going on, and what's been done so far. 1) hooked up battery charger to boost - accidentally reversed the cables 2) multiple "explosive" sparks and small flames coming from battery terminals and vents 3) car will not start or turn over 4) headlights will come on 5) no electrical components inside car will operate 6) all fuses have been checked (supposedly) 7) tester says battery polarity is not reversed   Any ideas? I was thinking either a fusible link to the starter, or the ECU took a deadly shot of voltage. Replies to this message: Mr_Shiftright (Jan 22, 2008 5:32 pm)

Replying to: cprdnick (Jan 22, 2008 8:33 am) First I'd check the battery itself for shorted plates internally. It might have enough juice to dimly light the headlights but not turn over the starter, which requires mucho amperage. If the battery passes a load test, then I'd trace the cable down to the starter motor, and also any other hot lead off the battery to a fusible link. I'd also PULL the fuses and check them all with an ohm meter, and unscrew the fuse box and look behind it for burned wiring. I'm not seeing the connection between a damaged ECM and all these other problems. I'm thinking more about wiring and fuses. It would be great to have a wiring diagram of this car.

It was the main power fuse (100 amp). Was kind of hard to see in the spot where it was located and the fuse panel cover says it was supposed to be somewhere else. Thanks anyways folks. Four bucks later and the car's running.
