Rich, it sounds like it could be a bad PCV hose. There was a recall for 2002-2003s but it affected mine as well and I had to replace it. Here’s the recall notice: http://mpvclub.com/recalls.php?id=17

Here’s a new PCV hose on ThePartsBin.com for $17.95+s/h. The hose is listed as a 2002-2003 but should work fine for your ‘04.

Is it possible we could get a class action lawsuit here? Ignition coil problems have ruined two family vacations and put my kids at risk being stranded on busy highways, etc. Would anyone else be interested in finding an attorney that would represent each and every one of us here against Mazda? I just returned from a one week family vacation, 5 days of which were spent without transportation because our van was in the shop. I am beyond over this!

I have the same problem with my 2004 MPV van. I just had to get another one replaced (this will be 4) & the dealer charged me $400!! I tried to get Mazda to pay for it, but they refused & obviously care little about their customers. It should have been a recall, but Mazda would rather screw their customers!

PS Is anyone’s van also rusting prematurely?

Hi I have a 2005 MPV and it was running fine. Now it just cranks but won’t start. I hear the fuel pump kicking in but just won’t start. It seems like it wants to when the gas pedal is pressed but once release it boggs n shuts off. Any suggestions?

In 2004, I puchased a new MPV for my wife. I must say, it has been a perfect fit for her, and a good van for the family. Now, with nearly 70k on it, we are addressing a second coil issue. After reading all the comments, I now know this is going to be a re-occurring problem. After these latest repairs, we will be selling the van. I must admit, I will miss it. Thank you all for the insight.

Replacing ignition coils in 2004 Mazda MPV:

GREAT information! My Bride and I purchased an MPV 2004 mazda, with 79K miles, in February. We started having problems with hesitation and jerking, starting in April.

So, I found this fantastic site which provided the link required to purchase six new ignition coils and six new plugs – $150. I then took the new parts to my honest mechanic who replaced all six, both sets, for $250. Total cost = $400.

We just took a vacation to Las Vegas, 625 miles round trip. The MPV ran GREAT!

post script: A knowledgeable Checker Auto Part specialist echoed the fact that original Mazda ignition coils were JUNK. The after market replacements have proven to be much more dependable.

So, take the advice on this site, replace all six coils and plugs! Your MPV minivan will run like new! Six cylinder powered engine, unleashed!

Thanks for all the fantastic advice!

Happy MPV owner in Phoenix AZ!

An update:

Yesterday morning, I couldn’t touch the accelerator without the check-engine light flashing (with loss of power and rough riding). Today, I waited until 4pm when it was over 90 degrees outside. I let the MPV warm up for 5 minutes, and then I drove it around and couldn’t make the check engine light flash once. It does look like something is getting wet.

Our 2003 MPV just had a cylinder #5 misfire CEL (and loss of power) both before and after a coil #5 replacement (all spark plugs were also replaced).

Can anyone comment on the claim by ‘buzzk’ that the factory coils have a vent which permits water to short the plugs:

This explanation would account for the fact that our failures occur while travelling and on holidays (when our car is not in a garage) and after rainfalls and in the morning.

Has anyone identified coils which do or do not have this venting?
