the 0170/73 are common. you have a couple of vacuum leaks. there are 3 actual "tees" and a bunch of "Y"s that connect about 21 feet of vacuum line. one or more of the tees are broke, and air is coming in. easy fix, but you gotta take off the whole intake to get to them rascals. lotsa labor, lotsa stuff has to come off. btdt. we have 2 99s'. if you cannot do the work yourself, the car will eat your lunch. get rid of it.
p0303 is misfire on #3 cyl. most likely the coil is bad. the rt bank(rear) coils get way more heat than the fronts. and #3 is the middle one back there. also, because of the intense labor to get to the plugs, lotsa places you take the car to will charge you for the plug change, but never do it, because it takes a couple hours to get to them suckers. when i do it, i make sure i got new plugs, and i take a known good set of coils and replace them. you can switch the coils from the back to the front, because the front ones will outlast the rears. and if someone says to switch #3 coil with another and see if the miss follows, has NEVER done this job on a 2.3.
p0431 is your post cat 02 sensor telling you the cat is dying. that, along with 1173(heated o2 sensor, same bank) tells me somehow you fubar'd the cat. you need to take care of the fuel problem, because if fuel fubar'd the sensor and the cat, if you just put another one on, it will kill them, too

what motor do you have? the 2.5 has hydraulic lifters, and if they are stuck, they will make a racket. also, if the timing belt tensioner is bad, it will make a sound very much like a bad lifter, and the sound goes away when the motor is revved. the 2.3 has solid lash adjusters, so if they were bad, you would have noise all the time. however, the tensioner can make a lifter noise on the 2.3, too. if the knock is coming from deep inside the motor, you got BIIIIG problems

most common is the motor is gummed up. you can take it out and clean it. next is the relay, it can go bad. to remove the motor, you pull the lower panel under the turn signal switch. you can then see the motor. it is held in by 4 screws, but 2 of them are covered by the panel right next to the one removed. i make 2 holes in the panel to access the screws, pull the motor, take it apart, clean, regrease, reinstall, and hope

#4005 of 4030 Grinding noise solved
Sep 16, 2010 (1:12 pm)
Almost a year ago I posted about a grinding noise when I started my Millenia S.
Had starter, flywheel, another starter, installed by my local mechanics. Finally,
I talked with a Mazda mechanic and he said that he would recommend an OE Mazda starter. I did, and the problem seems to be fixed.
I also get only OE Mazda brake pads since they do not shed an excessive amount of brake dust.

See my recent post about my starter problem being solved. About the flywheel,
I had mine replaced (there were several teeth broken off) at a local, reputable,
transmission shop.(Not AAMCO) Cost: $600. A dealer will charge in the range of $1700.
#4007 of 4030 2002 mazda millenia 2.5L Engin noise
Oct 04, 2010 (9:51 am)
2002 mazda millenia 2.5L base model got loud engine noise after start up or idling. the noise seems to almost dissappear or much less noticable when rpm above 2000rpm. Check engine light on with code 0300, 0350 and 0421. Changed all spark plugs recently. The local mechanics told me the noise seems from inside timing belt cover, front of oil pan, rear upper valve train and water pump. I read one post said bad timing belt tensioner could cause engine noise/knocking. Timing belt never replaced on this car. Can anyone kindly provide the advice or similar experience? Many thanks.

It seems I get the similar problems (post 4007). I just wonder if you have found the causes. Thanks.
#4009 of 4030 02 2.5 with leaking valve cover gasket
Nov 14, 2010 (4:58 pm)
I have a 2002 P and the dealer and oil change shop have both told me that I have a leaking valve cover gasket. I guess this is the reason that I smell a burning smell after I drive for awhile. Is this a serious problem that needs immediate attention? Also, is this a difficult and expensive repair? Please note that I also need to replace my EGR valve(??) and would like to know if this is costly.
