2000 millenia s 95000 miles. Changed the plugs found the typical oil in the oil wells. Changed the valve cover gaskets which took us 8 hrs to do but saved over $600. Also changed the 2 of the 02 sensors couple of years ago. Now I have this p0431 code which indicates the catalytic converter. I might not replace that until the gas mileage gets really bad. Will this hurt anything else? great car just expensive when somthing goes out. anyone changed out the timing belt themselves?

I have read about changing the timing belt on another forum. I read a technical guide the guy added about his experiences. Access is the key issue. Remove the steering pump. He said he had to cut the rear timing belt cover in half to get it out. He said he had to raise the engine to get at the alternator tensioner bolt, but it would be better to drill a hole in the frame so you could always get it out without raising the engine I think. Other than that, it is just a matter of getting a manual and following the steps.

2001 Millenia S - Compressor Problems

I have a 2001 Millenia S and have recently discovered I need a new/repaired Lysholm Compressor and have been given an estimate of $4,200.
The vehicle has 112k miles and I am not sure the vehicle is worth that much, prior to this there have been no major problems.
Is this worth repairing or is it a sign of more to come?

How did they diagnose the s/c going out? Have you changed out the timing belt mazda gave me a quote of 1200 CRAZY. If you do change the s/c you should replace the valve cover gaskets also since you are in there.

I have changed the timing belt just recently actually, they looked at the S/C but the biggest signs were burning oil and an incredible amount of exhaust at startup and any time during acceleration

What kind of gas are you using, have you changed your fuel filter? It could be your IAC ( Ilde Air Control valve). It cost too!! $450.00

Yea, thats a tough call and the price sounds about right, unless you plan on doing the work yourself. How many more miles do you expect to get out of the engine? 140K? 160K? You may want to consider replacing with a used, low mileage engine - you may even be able to have that done for less money.

It won't cost much for a shop to hook up a diagnostic code reader and see what code is set. From there, you can get a better idea about why it is on. It may be something minor. You cannot pass smog with the indicator light on.
