Engine Noise

Written by: 5th_mazda on Sep 06, 2009 08:25 PM

My 2001 Millenia just starting making an engine noise that when I heard it for the first time sounded like rod/valve train knock or maybe an exhaust leak. The noise only happens when you first start the engine after it has sit (the longer it sits the longer the noise lasts). The noise goes away as you rev the engine up much past 1800-2000 rpm and completely goes away ... Read More...

Re: 2000 Mazda Millenia catalytic converter replacement [kindasimpl]

0300 is random missfire. when was the last time you changed plugs? and which plugs did you use? i am guessing that from your codes, you have a 2.3 mc motor. be very careful, most aftermarket places do not have the correct info on plugs for the mc motor. the gap MUST be .7-.8mm. NOT 1.1mm, like most of the stores think. if you do not fix the random miss, you will be buying ... Read More...

Also have a 2000 Millenia S model with 87k miles on it. Did not trigger a warning light or codes, but continued to "buck" at speeds around 55mph, as if it was missing. the Millinenia forum suggested the oxygen sensor located next to the air filter, so I took it apart and sprayed contact cleaner on the wires. This worked for a week or so and then it began again. My mazda ... Read More...

2000 Mazda Millenia catalytic converter replacement

Written by: kindasimpl on Jun 24, 2008 08:01 AM

Our 2000 is giving off codes PO300 and PO431. From my research it indicates the catalytic converter as the O2 sensor going would not trigger the 431 code also. I found several on-line as a replacement but don't know which to choose. Also can a "small town" mechanic do the job or do I need to take it into the city? Is there anything else I should go ahead and replace at ... Read More...

Written by: taxijack on Apr 25, 2008 03:26 AM

I have a 2000 Mazda Millenia and love it. I have read the site looking for a fix to my problem but haven't seen alot on my error codes.

I took the Mazda into the shop because now it is running ruff when I stop at a light. I do here a vacum leak at top of engine ... Read More...

Millenia Engine Blew up

Written by: wilcor on Jan 01, 2008 08:16 AM

I have a 2000 base model with a straight six cylinder engine that threw a rod through the crankcase at 58,000 miles. This car was well maintained and driven by my slow poke wife since it was new. This occurred after the 60,000 mile service was done and the timing belt changed two months before it blew up. It was out of warranty and the Mazda factory rep supposedly inspected ... Read More...

Mazda Millenia EGR problem

Re: EGR problem with 1999 Mazda Millennia [jazzyman26]

Written by: chozen on Sep 10, 2007 00:36 PM

I have had a 1999 and a 2000 Millenia. The EGR value issue is a big chaotic problem, yet with a simple solution. If you take the intake off the throttle body, and remove the four screws that hold the throttle body on and remove it also. You WILL see a really clogged hole in the bottom. If you take some engine cleaner, and spray it in it will break up the build up. I usually ... Read More...

Re: Bogging issuses!! [jmacneill]

Written by: mazdaphobic on Apr 13, 2007 10:00 PM

If when you hit the gas it revs up but do not respond by accelerating then it seems like a timing belt problem. If the car loses power while driving then the engine may need to be rebuilt(egg shaped cylinders). This is based on what my mechanic told me about my car. I do not know if your car has TCS which runs off the vacuum system. A bad valve could cause this problem but ... Read More...
