1250 is the fuel pressure regulator and 1569 is variable timing control solenoid. Both will cause rough running. I would check the regulator out first.

I have a 2002 Mazda Protege5 that now has a loud, continuous metallic 'rattle' coming from the top, front of the engine. How can I locate the problem and how can I fix it?

code p0660 refers to intake manifold tuning valve , bank 1 --circuit open===causes --wiring---intake tuning valve

code p0302 refers to cylinder 2 --misfire detected ===causes --engine mechanical fault--wiring ignition /fuel system---injector---ECT/MAF sensor---ECM
form you description I suggest that you have a compression test done and check for a loose valve seat insert for no 2 cylinder
That would account for the rattle and loss of power and misfire for that cylinder

Where is the EGR valve on a mazda protege 5

I own a 2002 Mazda Protege5 with the FS2.0 Motor. The EGR Valve is located below the throttle-body. You must take off the Intake tube to get a good view of it. To replace it I think you might have to take off the throttle-body, but I'm not sure about that...(yet)

NOTE: Mazda put out a technical note stating that "if your car has sat for a long time, the egr valve could be damaged by moisture (rain) and will need to be replaced". My 2002 Protege sat for 3 weeks and the rain caused this exact issue and had to be replaced. How did I know? The engine light came on (after never coming on) and the car had an extremely rough idle. Total cost was ~$400 (ouch).

Lost of acceleration power, no power going up a slight incline. however in park engine runs a little rough, but will accelerate but when put in drive has no power

This may be caused by a misfire, this can be caused due to a tuneup, have the plugs and sparkplug wires checked, also is the check engine light on? if so scan the codes, many autopart stores will scan for free if there are misfire codes then i would start with a complete tune up and go from there, the most common problem when this happens is a tuneup is needed or the fuelpump is weak, to test the fuelpump you will need to have a pressure tester put on the fuel rail, hope this helps. good luck.

Code po705 mazda protege lx shaking rough start

The Code you refer to is P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input). It is a possiblility that because this code is present, this sensor is malfunctioning. If it is malfunctioning, that means the engine needs to "guess" the value that this sensor is responsible for. In most cases when this happens, the engine will go for a value that ensures the car runs. The engine will not try to run smooth or efficently, it will only try to run. It is my guess that if you have the sensor checked and replaced, the problem might be fixed. Please let me know if this answers your question and please rate my response. Thank you

It is not either simple or cheap.

You will need a mechanic with knowledge of that tranny or a ntransmission shop to do the repairs.

Expect to pay between $600 - $850

2002 Mazda protege5 check engine light says faulty transmission tr switch. I'm told it is a job you can do on your own but how??? Transmission shop wants $150 just to see if that is the problem

Well if you dont want to KNOW what it is, are you willing to lose money guessing? The TR switch COULD be bad, or out of adjustment, or the bushing for the cable bad. Its not to bad to replace. its right on top of the trans, but you need to know what you are doing. I would think its a dealer only part.

Rear view mirror

Has the mirror previously been capable of providing a view of the left lane?
If it did not, the "clicking" sound is simply an indicator informing the user that the angle limit has been reached, the mirror will not travel any further.
Simply purchase a pair of stick on Convex mirrors, they are about 1.5" in diameter,they do the job perfectly. I know this because I've got them on my Protege5 mirrors.
