I am a diagnostic mechanic so obviously I do all my own repairs. My MPV was 3 years old when I got it. I have owned dozens of vehicles including a Lada, Renault LeCar, Austin American, K-car, Omni, etc.... but this MPV thing has been hands down the worst vehicle I have ever owned. I have over 7 years experience as a warranty manager and I went face to face with Mazda for over a year to get them to honor their corrosion warranty for two front doors and a hood that rusted through before it was 4 years old. When they finally gave in they acted like it was out of the kindness of their heart "B.S." Corrosion warranty is a law not a gift. About 6 months ago it started doing the Stop light Hokey Poky so bad people were starring, I'm sure they thought I was reenacting the driving scene from "Evening at the Roxbury". I was getting a Cylinder 4 misfire code so I installed a new coil, then all new plugs, then repaired a vacuum leak - no better. I have tested fuel pressure, compression and spray patterns for all the injectors all good! I removed upstream O2 sensors to see if converters were plugged - they were not. All the components checked out. I suspect that it is the wire harness or PCM. I found a fellow near my home that offered me his 2003 for $100 for parts but it hasn't run in over a year, he bought his new, said it was in the shop every week when new and he gave up on it a couple years after warranty was off. With just 102,000 miles on mine I am sending it to the crusher. The junk yard will give me $100 for it if I drive it there, he said it is worth nothing because no one around here is fixing them, local junk yards have munched over half a dozen of them this spring. I said I would give it to him for nothing if he let me push the "Crush" button, were still working on that. I am quite confident that I could find the problem If I wanted to spend my summer looking for it but I hate the thing so bad that I can't even stand to look at it any more. It is a rusted out piece of ^&%$^ with a cracked windshield - oh ya there are several around here on which the windshield cracked from the bottom up for no apparent reason, the guy that offered me his for $100 said he replaced his but it cracked again 3 weeks later! Then there was the cooling fan module, there was a recall for it but local dealer said my serial # wasn't under it so I had to pay $150 for the module!! I did Ford warranty for several years and I was able to get recalled items covered for vehicles that had same failure but build dates were out of recall range. This was a bad product from a cheep Wiesel of a company that has no interest in customer satisfaction. I would love to see someone use the transmission out of mine... I think it is still good. I would be happy to let it go for $200 maybe less if I got the chance to Kick the %$^* out of it before it goes. I am keeping the tires though.

WOW!! $300 for the back 3 plugs! I can take my intake manifold off in my sleep! What a bunch of crooks. The intake gasket is totally reusable, I would do all 6 for $100 plus parts, all 6 should be no more than 3 hours lbr at the dealer. The grunting or creaking in the front end could also be the lower ball joint - they tend to seize, bad news is that you have to get the lower control arm as a unit... about $500 in Canada at the dealer for the part alone. I have been able to source aftermarket from same supplier that sells to Mazda for less than half, be careful though, there are cheep units that will literally pop apart.

I had the same problem with coils, but when i first complained about the van jumping they told me to drive it until the engine light came on , when I took it back for service I was told the cat converter was bad now I am very upset I have had to pay over $4,000 in repairs and now I have been told to get rid of the van I feel this is too soon to scrap a 2003 I paid $33,000

If an MPV bucks at idle, it is very likely due to a major vacuum leak in the PCV hose that attaches the back of the intake manifold under the cowl. The hose makes a right angle bend (down toward the ground) immediately after exiting the intake manifold. The hose is a common point of value in all 2000-2006 Mazdas but the OE hose in 2002-2003 MPVs was particularly prone to early failure. Mazda issued a recall for these model years and replaced the part with a second generation design that typically lasts only two or three years before it fails in exactly the same place. The current part, which is a third generation design is more robust but it costs about $80 from a Mazda dealer.
MPV coils do often fail but the bucking at idle symptom screams "PCV hose leak". Do a google search for
site:mpvclub.com PCV hose vacuum leak
to find lots of threads on this topic.
If you have prior experience working on MPVs to fix this problem, the hose is easy to replace. But it is difficult the first time because your have to do everything by feel. You cannot see the hose clamp or the right angle bend unless you remove the intake manifold. At mpvclub.com, you will also find instructions on how to make a robust homebrew replace hose for $10-20.

I had some big problems early on in the first 2 years. 2002 MPV ES. first off there was a cracked manifold which needed to be replaced. 2 years later in 2004, the transmission went. My guess is I had less than 25k miles on it. It was replaced under warranty. For the most part have not had any other problems until recently, started hearing almost a metallic clinging for a couple months, now I am getting the bucking, in what feels like a transmission problem. Hopefully its the coil thing I have been reading about, but am bringing it to my mechanic because I don't trust the dealer. Van now has 108k miles.

So I just got the 2000 MPV from a private party and he told me that it was in great condition and everything was new in it. Since I got it, it has bucked and had a whining sound. Since then it will not accelerate in D you have to start in 1st then shift into 2nd as the rpms rev up. Since then it jumps worse and slam's into gear. After u get to 40my MPH u can shift it in D. I'm guessing its the transmission. Fluid is good and hoses r fine so has anyone else had this problem? HELP

#184 of 191 Engine Short r/t plug undone
Aug 05, 2012 (6:19 am)
I recently took our MPV 2004 to the dealer because it was stuttering when driving and accelerating. We were told it was an electrical short that would cost $3000. The plug that the short is in was left unplugged during the last vehicle maintenance. When we told them they were the last ones to do maintenance they said it wasn't caused by the plug not being connected. What can I do?

If the problem happened immediately after your last maintenance it was caused by whomever messed up. If not, then it's unlikely related to what they did. I'd really like to know what exactly was "unplugged" during vehicle maintenance, though? I am struggling to think of even a fluid or belt change that would require unplugging of anything electrical.
Are you sure this is transmission related, though? I only ask because my local mazda dealer said the stuttering I was getting under mild acceleration was transmission related. I doubted it, and I was right; it was the VERY common ignition coil problem, which can often not present with any check engine light and give inconsistent stuttering, generally under mild throttle at lowish speeds. Diagnosing can at times be tricky because as mentioned the CEL won't always fire.

The plug that the short is in was left unplugged during the last vehicle maintenance.
If that were true your van would have begun stuttering the second you started to leave the dealership. Plug/coil problems would be immediately noticeable.
I'd take it to any dealership.
