95 Protégé runs great at idle but it loses power as soon as cooling fan turns on???
I'm new to this forum and I hope somebody can help me out.!
I have a 1995 Mazda Protégé 1.5 that smoked alot and after just a minute or two it would stop running. The EGR and Throttle Position Sensors were replaced recently though..!
Found out that the piston rings were bad and replaced them along with all necessary gaskets, Timing Belt, Water Pump. The engine runs great now, but after 30 minutes running at idle, it suddenly stopped running. I reset the timing and the idle and it's running good again. I then took it for a test drive and after a mile it lost power and when I stepped on the accelerator to give it gas, it would sputter and the car did not go faster than 20 miles per hour.
After 15 minutes I started the engine again, ran fine and took it for another drive, this time I went about 5 miles or so, and then it lost power again.! At idle, the motor runs very good, but as soon as I step on the accelerator the engine bogs out and loses power.! What could the the cause of this? 02 sensors, Crank Sensor...??? Any ideas would be greatly appreciated.

RE: 95 Protégé runs rough and loses power after it warms up
that sounds like injectors pull out your sprak plugs and leave the hole open and try starting your engine if it sprays fuel out then the injector is working if it doesn't thats your problem.

The injectors are fine.
I had it diagnosed and I got 4 codes. A P0750, P0755 and P0760 on the transmission (Shift solenoid malfunctions) and another for the Crank Sensor that has been replaced already. How hard is it to replace these solenoid packs for the codes above and does this has anything to do with loosing power while driving.?

all your shift soleniods are mounted on the transmition valve body all mazda cars use power controlled soleniods. you can olm the solenoid and the current should read 0.90 - 1.20 v, you can also check the wireing if you olm the power wire running to the fuse box it should read 12v if not replace the fuse, if you don't read the voltage i gave you above on the soleniod replace the soleniod
that may be the reason for your power loss. when was the last time you had a tune? like replacing the fuel filter, checking spark plugs and so on. And also stay away from no name ****ty oil cause that just results in engine problems such as seals going,engine wear and so on.

i forgot to tell you how to replace them lol its basic wireing you take out the soleniod retaining clip and pull out the soleniod then just connect the wires into the new soleniod.
