he then told me two days later that I have to replace all the coil.
 
It would be a miracle for all 6 coils to fail at the same time. No, your mechanic is not guessing. He is incompetent. Take your MPV somewhere else.
 
If he did replace #2 coil, he should have asked you if you wanted #1 and #3 replaced since they are in the back of engine as well... would have saved you a lot in labor.

Thanks for your info. Now I'm thinking that this mechanic is just trying to reap me off. I tried to ask him for my old parts and he mentioned that he misplace them. I'm sure that he only replace cylinders in the front.. The back three can be tricky? what does that mean? im taking my car to another mechanic to take a look at it, or do it myself to ensure that im not gonna be reap off.. any suggestions?
 
Thanks again

There are step by step directions, with photos, on how to replace the back coils at the "MPVClub.com". A lot of people at the site say it is fairly easy.

The back three can be tricky?
 
With the back 3 coils (#'s 1-3) you have to take off the intake manifold to get to them... takes about an hour and a half I believe.

#51 of 75 2004 MPV stops w/o warning, restarts easily by buzzk

Oct 11, 2009 (8:05 pm)

Our 2004 MPV recently has the engine occassionally just quit - usually when stopping, especially suddenly, but at least twice it happenned at hiway speeds when on cruise at 60+... both of those times at the same spot in the road, where the hiway dips down into a sort of mini-vally, then comes back up a short hill. It dies abt where the road levels out again. All panel lights come on, but it starts quickly & easily & runs flawlessly [til next time] after that. panel lights go out instantly & the code reader only once had a pending code abt the transmission range selector switch, which cleared w/next run & at all other times [abt a dozen in the last couple months] there is no code at all, pending or otherwise. I've checked a lot of obvious stuff & found nothing wrong; I think it's probably a bad ignition switch.. advice? anybody had this problem?
 
thx, BK

Had the same problem. Cleaned idle air solenide mounted on top of throttle body. Took it off, cleaned it with gumout. The little piston needs to close and it gets carbon in it. Where the idle air control bolts on to the manifold the passage was carboned. Sprayed a little gum out and then inserted a small brush to clean carbon. Also cleaned throttle body. Inside the throttle body there's a plate that opens and closes when you open the throttle. It was all carboned. So far so good!!

#54 of 75 Coil trouble by shopdog97

Dec 04, 2009 (6:06 pm)

Why is it that these coils seem to go out all the time? I've read here on these blogs and postings on the electrical forum and I see that a lot of you folks have had a lot of problems with them. I posted a story on the electrical issue blog regarding a friend from church who has an 04' MPV and she said she has had to replace them frequently and sometimes the SAME ONES! This is insanity to me! What do the powers that be at Mazda have to say about this? This lady went to her mom's home in NC for the Thanksgiving holiday, and on the way there had a problem where the thing felt like it was going to shut down any minute. The 3 hour trip took her nearly 5 hours and she took it to a local garage there for $400 bucks worth of work, but she also said that she spent nearly that much here locally just a few months ago. She called me this morning and told me that the van was acting up again and had very little power when she hit the gas and the check engine light came on again. Are these things possessed?? Now I read on here and in the other blog that these coils are prone to fail when water gets on them, is that correct? I've offered to help this wonderful Godly lady, and I'd sure appreciate any advice you can give me on this. I'm gonna go to her home soon and scan her computer with my OBD2 within the next few days. Thanks and I hope you all have a wonder Holiday season!

you might look at some of my other posts.. the coils that came from the factory on the 2004 MPV we love to drive, have a design that is simply idiotic; they have a built-in VENT that allows water/steam/etc, to get into the plug well & short out the spark; it is high voltage [like all spark systems] & is easily shorted. I got aftermarket, cheap, much plainer looking, black rubber coils from ebay BUT.. fit perfectly and NO VENT! - sealed the tops of the spark plug wells to keep out moisture & have had NO PROBLEMS w/coils since. BTW sealing moisture out of spark plug wells has been standard practice for DECADES. It does cost a lot to replace them due have to remove the intake manifold to get at the back 3. quite possibly garages are getting the old-style OEM vented coils but I easily got the better design from a regular ebay supplier. Abt 3 or 4 yrs ago they were abt $120.00 for a set of 6. Also I have removed, cleaned, dried & replaced the original coils [til I could get the new ones] & they worked for a while - so, did they REALLY replace your friends' coils?
Good luck, BK
