Saved us a BUNCH of money and likely helped my wife avoid a serious accident with our MPV. Took our car back to the mechanic for help on the stalling. They were open to looking at this thread but weren't sure that it would solve the problem. I asked them to replace the IAC since it was worth the risk and this car (our main family car) was nearly undriveable. Cost me about $100 to have it installed. The car hasn't stalled since. A great example of how the web can do some great stuff. Thanks again. THANK YOU for this post. Saved us a BUNCH of money and likely helped my wife avoid a serious accident with our MPV.

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 <a href="http://www.thepartsbin.com/catalog/?N=1667%2B11082%2B4294962955&uts=true&Ntt=W0133-1834887&x=0&y=0" rel="nofollow">Here's a new PCV hose on ThePartsBin.com for $17.95+s/h.</a> The hose is listed as a 2002-2003 but should work fine for your '04.

The engine surges when stopped at a redlight. The vehicle would jump forward if the brake is not held down. This is different than the coil problem (already experienced that one). I have replaced the IAC valve (which the old one wasn't that dirty) but this did not fix the problem. I was wondering if it could be a sensor or hose issue and if so where would I look?

I'm driving along and it feels like is sputters, or hesitating as I accelerate along the highway. Happend in May after a 1 hr drive & then again in July after a 2 hr ride. The AC is on and then I won't happen for week. Is this the IAC issue that I can get at AutoZone. My Firestone mechanic said it was a Mazda recall on PCM part & I would have to have Mazda take a look. What a pain...help? My 2004 MPV is hit or miss with how the engine runs. I’m driving along and it feels like is sputters, or hesitating as I accelerate along the highway.

We had the car stall x 3 and then brought it to a mechanic here in Italy. They were confused, so I called a dealership in New York, who was happy to help. The recommended this replacement and it worked like a charm. The process was very easy. Everything was fine for 5-6 months, but now I have another problem. When I start the MPV, it idles in the 1500 range, and putting it into gear feels like riding a horse which is anxious to get out of the gate. If I wait 30 seconds, then rev the engine, it will drop to 800 RPM and drive without problem until I start the car again. I'm not sure why this happens and am guessing it isn't a hose leak, as it only is an issue on startup. Could it be a sensor? Replacing the IAC is likely to help – it did on my 2006.
