    New to my daughter 03 p5....Need to bring it up to snuff....

    Carfax def doesn't show everything. But... if it does show a T-Belt change then you can be reasonably sure that it was done at the indicated time. Plus, it can show where the car was serviced and you can call them and find out more info. Just one of the tools you can use.

    New to my daughter 03 p5....Need to bring it up to snuff....

    If you run a carfax it may show maintenance, particularly the timing belt. If you don't have an OBDII scanner, get one. These cars tend to have various emissions issues. The most common ones are easy to fix and easy to figure out what is wrong if you know the code that is causing the CEL. If...

    Radiator replacement - detailed with photos

    Just did this today. Pretty good write-up. Some things to note... 1) get some hose clips in case you can't re-use the ones you have. 2) when putting your hose clips back on 'seat' them in the indentations of your hose. This will keep it tighter. 3) Those smaller hoses on the bottom are for...

    Mazda Protege Rear Drum brake questions

    I believe I need to replace the drum on the rear for my LX. This guy... https://www.youtube.com/watch?v=7rRViAdCkGQ mentions that you can put a bolt in the extra hole on the drum to force the drums off. I have 300k on this car and it is very rusty. I expect the drums will be very difficult to...

    p0300 advice on diagnosing

    Coil Pack is a Standard Motor Product (so not OEM, not sure if it qualifies as 'cheap generic') it was replaced due to throwing a code. Several months later I got a code again and since the spark plugs were due to be replaced in a couple of thousand miles I replaced them with NGK Platinum...

    p0300 advice on diagnosing

    What I have done... 1) traded both coil packs with my other P5. 2) Cleaned the MAF, checked the air intake hose after the MAF for cracks, and checked for Vacuum leaks as best as I can. 3) can of seafoam in gas. 4) pulled a single spark plug. It looked good, a very little oil around the top...

    p0300 advice on diagnosing

    Not guessing. I am looking at the mazda protege service manual and the 24 step procedure for p0300 and the number of possible causes that are listed. You may be correct that this code will not re-occur or that an additional code will surface. But until then I'd like some help in narrowing the...

    p0300 advice on diagnosing

    Yes, well aware that p0300 is a generic code and a starting point for diagnostics. Other than clearing the code and doing a drive cycle do you have any other suggestions for diagnostics? The service manual mentions CKP Sensor and CMP sensor as possibilities. Where are these and what do they...

    p0300 advice on diagnosing

    Got a p0300 today. No other codes. Plugs and wires have been recently replaced. One of the coil packs has also recently been replaced. I am not sure what it could be I've always gotten a 301 or 302 and not the generic 300. Any ideas?

    Jumping then stalls

    Correct. Again if you have an OBDII scanner you can check to see if all the OBDII checks have completed or if some are still pending. If they are still pending then your ECU is trying to do all the checks and tune your car for its condition. You can speed this up by running the Mazda Drive...

    Strut Replacement advice

    Ended up using the Monroe quick struts. Some notes on the install for the next person... Good video here... 1) One of the top bolts sticks out further than the others, so you will need a 14 mm deep socket to remove that one. 2) My quick struts came with new nuts for the top bolts. But...

    Well, I do have the sportronic. Install wasn't that bad. Didn't really have to adjust anything once I slapped it on. Shifted through the gears about 50 times. So far no issues.
