#3153 of 3742 acceleration problems, first time poster
Jun 21, 2007 (1:41 pm)
First time poster, who is loving all the info i can get on cars from this site!! I have a 2000 or 2002 mazda protege (its at the shop or i would look to see the exact year, i am inept with car issues sorry). The car was bought used from our family friend mechanic and has around 50000 miles on it. Lately it has been giving me serious trouble when going from stop to go. So much that i took it in to get looked at. Our mechanic says he doesn't know and to take it to a dealer.
Anyway the problem is i can be at a stop light and when the light turns green I push the gas and the car struggles to go. I can feel the engine trying to go and after sometimes up to 10 seconds the car spurts to life. This happens at intersections w/ lights and stop signs, when making turns that i slow down to turn and try to speed back up after making the turn, when i move back out of spots and then put the car in gear. The check engine light has been on for months, which i have had checked out but was told that it is a just an error. My oil was changed approx 1 month ago and I keep that up to date. This problem has been getting worse and is dangerous when i am making turns and trying to merge. Any suggestions on what this could be before i take it to a dealer so I don't get ripped off. I am super grateful for any advice!!

It sounds like a problem with your Mass Air Flow Sensor (MAFS) from the symptoms you've described. It may also be a clogged fuel filter but the symptoms are similar to a number of other problems. You can have the error codes on your car computer read for free at Auto Zone and they may be able to clear the error codes so you get newer input. That's the first step you need to take...
#3156 of 3742 Accelerate to your dealer

Yes, it could be a number of problems. I had an issue with the EGR valve that gave me similar symptoms. I agree with your mechanic who suggested you go to the dealer; better that than getting involved in a serious incident. If there's more than one Mazda dealership in your neighborhood, you may want to ask which is the better for service. My experience with Mazda dealerships has been fine.
#3157 of 3742 help with a fuel pump
Jun 22, 2007 (2:41 pm)
Does anyone know how many volts I should have at the fuel pump of a 91 protege? I only have 7, and the open relay ohms ok with 12 volts coming out of it on the one side. I am not sure where to go next. Any advice would be appreciated.

'99-'00 Proteges with the 1.6L engine had a voluntary recall on the MAS. It could lead to the symptoms you describe (did in my '99LX).
An EGR that is stuck open can also lead to similar symptoms. This is normally only open under certain conditions.
#3159 of 3742 Rear Piston Stuck In Calipers
Jul 07, 2007 (4:06 pm)
Greetings.. I'm a newbie here & forgive me if this topic was discussed earlier. I have a 2001 Protege 2.0. I'll get right to the point.
I removed master cylinder cap..removed e- brake cable...removed caliper..removed pads (left inner one in to be used for pressure against c-clamp)..Problem...Rear pistons will not move in to make room for the new pads. I tried w/ bleeder valve open too...will not push in. I was told that the rear pistons need to be screwed in..upon examination, there are no notches or grooves or anything on the piston to insert piston removal tool.What am I overlooking? I think I explained ( I hope so ) everything. Any advice will be appreciated. And thanks for your time. Jim

Motor mounts were shot replaced with AWR racing mounts. Alternator was running constantly because of bad battery and to much power draw from my stereo system. Fixed.

alternator running constantly? i've never known one not to when the engine is running. you think your vehicle's systems are being run exclusively off the battery?
i think not.
perhaps you meant your alternator was being ruined constantly because of a bad battery and too much power draw from your stereo.
that i could see.
