Replying to: tcc21 (May 02, 2009 9:19 pm) Could some of the "transmission problems" the dealers can't identify possibly be misfirings due to bad coils?   Whem my first coil went out maybe 2 years after we bought our 04 MPV, the car felt really clunky in reverse. I thought it was a tranny problem and took it to the dealer. The tech couldn't find anything, and since the coil problem was intermittent the code reader didn't find the problem. It took two visits until they identified the problem properly.   Last month we found the MPV surging and feeling choppy at times, so we correctly surmised it was another coil issue. This time two of them weren't firing off and on, so sometimes it felt like a transmission problem. Replies to this message: tcc21 (May 04, 2009 7:38 pm)

Replying to: shirohniichan (May 04, 2009 10:29 am) Good point. I really don't know. I'm not a mechanic and never had that coil thing hit on my MPV....that I know of. My check engine light has come on due to water getting into the spark plug well on the front during several different rain storms I drove in. Once after I washed the engine off it came on for about 4 days and finally dried out and turned off. The other times it was due to a catalytic situation. That seems to have gone away now since the warmer weather came. I had it turned off - the light that is - at AutoZone for free. I hate to be such a debbie downer about the unit. I DO like so many things about the old tub...but I know it's days are numbered. I am backing off on the miles now so maybe it will last a bit longer. I use to drive it quite a bit - hence - the higher mileage. I went thru the whole tranny deal back in 04 and since then it's been ok. Some funky shifts but not that unusual. Tranny's are so complicated now with all the electronics involved. They are sweet when they work though!

My 2000 MPV LX has 95,000 miles. It has major engine problems. For the last several years (3 to 8) it had a very subtle occasional cylinder miss. For the first several years of ownership, the miss was almost unnoticeable (or I would have taken it in for warranty repair). The last three years, the miss became more prominent and frequent. I have taken it back in for diagnostics at and independent mechanic and at the Mazda dealer. I have personally replaced most of the electronics (ignition coil, spark plugs, wire set). The Mazda dealer ruled out the fuel injection system, emission control system, etc. The conclusion is that it is a major engine problem which would require taking the engine head off to inspect everything. We are starting to talk about over $1,000 in labor just to inspect and find the problem. The engine also has a pervasive coolant leak that has been hard to isolate. I am very happy with the entire car, other than the engine. I has been a major disappointment. I also have a 2003 Protoge5 with 75,000 miles and that 2.0L engine is an absolute gem. My 93 Miata has 180,000 miles, another gem. My conclusion is the Ford Duratech 2.5L V6 is major disappointment.

Replying to: tcc21 (May 02, 2009 9:19 pm) I DO know that the same like vehicle (Toyota or Honda) with 120K miles on it would not have these conditions. I should have spent the extra $5K at the time and went that route! Good luck! TCC   Really? Are you sure about that? I've had a 2001 Honda Odyssey needing a new transmission twice already. Turns out that Honda installed defective transmissions on the Odyssey from 1999-2004. The Acura CL, TL, MDX and Honda Accord suffered similar problems. The Third Generation Odyssey hasn't reported major transmission issues in case you're wondering. I've heard a rumor that it shares it's transmission with the Ridgeline. As for the Second Generation Sienna, it's had quite a few problems too. From electrical problems, to door spot welds constantly breaking. So if you think buying a Toyota or Honda is anymore troube free, think again. I personally would trade my $4500 transmission troubles for all of your minor problems any day.

Well, maybe there are a few bad apples out there with the Honda emblem on them....but I know of a person who owns a 2003 and they love it and my sister has a 2004 Sienna and it is very solid after 160K miles on it. Maybe I should have only mentioned Toyotas are better in the long run. I know the Blue Book on both Hondas and Toyotas are stronger in the long run than Mazdas! My 2003 MPV with 122K on it in excellent shape is around 7K dollars. The similar Sienna is worth more! Sorry if I mispoke for those of you having troubles with your Hondas. I know there are more bad apples with Mazda on them out there....I could go on about the Mazda 6's from 2003 -2006 - people I know that had those vehicles were not real happy.
#8158 of 8162 My 04 MPV - Great car but... by sm00ve Jun 06, 2009 (7:18 pm)
I only have one pet peeve with her. I can't find a manual for the van. NO one seems to carry one, internet or otherwise. The van is 5 years old, so surely someone should've taken one of these apart by now and wrote some notes or something. Haynes & Chiltons are starting to dissapoint me greatly...

Replying to: jipster (May 02, 2009 8:54 am) I just took our 2002 mpv into the dealer to get checked out because we had a loud noise near the catalytic converter...it was the flex exhaust pipe.The dealer put it on the "scope" to check for any other problems...he said there was none. 3 days later the van was running horrible..bouncing and erratic rpms...we had the exhaust hose replaced...much quieter but now engine light is on and it seems to have some sort of misfire....when the rpms get really low the breaks seem to harden and its hard to stop unless you go to the floor with the pedal. Shouldn't the dealer have noticed the brakes....they did have the tires off when we went to pick it up...not sure why, if there is a brake problem. Is it still safe to drive with the engine light flashing on and off until I can get back to the dealer? Van was fine until we got to the dealer...

Replying to: jipster (May 01, 2009 8:46 am) We bought ours NEW in July 2002. We have the 3.0 v6. Here is a list of things that have been repaired the last 7 years.   1. IAC valve - replaced part of TSB recall 2005 2. IAC valve - replaced again in 12/2008 after CEL came on. 3. Mass Air Flow sensor - cleaned in 5/2008 after CEL came on 4. Mass Air Flow sensor - replaced in 10/2008 after CEL came on   Other than that - there's been no problems. BTW - the hardest part is diagnosing these things ---- some mechanics just make guesses ... others are more knowledgeable than others. I used an independent mechanic for items 2 -4. I had to 'help' them understand the problem by giving a detailed history and telling them what I have heard from this board. True enough ---- I was right! He initially wanted to replace either the O2 sensors or the coils.   Right now - my MPV is in the shop ---- the fan is not working causing the engine to overheat. But after 124K miles --- and a cross country trip thru 100+ degree weather and wintry blizzards - it is difficult to complain.   I do change my oil every 6-8K and use synthetic or semi-synthetic.

Replying to: linda424 (Jun 10, 2009 10:24 am) What were the engine codes for the CEL?   My past engine codes have been PO171 and PO173. I've had a few more ... but previous experience has been the following:   1. IAC or EGR valve 2. Mass Air Flow sensor   The EGR valve leak produces very rough idling - if not jerky driving. The Mass Air Flow Sensor problem (usually either very dirty or worn out) - results in poor acceleration and low HP especially from 3rd gear to 4th and 5th and poor mileage.   Most mechanics will blame the O2 sensor or any of the coils. They can charge a lot for the labor for these ... so be aware. Read the codes... read the codes ... and research them carefully ... some mechanics are just as naive about these codes as any layperson --- yes, even the newbie mechanics at the dealerships!

Replying to: aa0526 (Jun 29, 2009 8:12 pm) BTW .. just got back from the mechanic ...   My two fans are not working ... something due to the wiring. If the two fans are connected directly - they run perfectly fine. The fuses are OK.   I will bring the van to an electrical shop.   I had them check the brakes ... after 124K, the brakes are still at 50% !!!
