#41 of 76 "shudder" at idle, 2003 Mazda MPV
Jul 20, 2009 (5:24 pm)
Hi, I've got an '03 with 138,000 clicks. So far, it's been extremely reliable and we've had no real problems. Now it "shudders' when I'm at a red light and it feels like it's going to stall out. Also acts the same going up a hill. Just had the coolant thermostat and seal replaced, as well as a "platinum plug" (#2 I believe) and the EGR valve gasket replaced because that's what the diagnostic check said to fix. Driving today the engine light came on (just got it back from the shop last week), and engine light flashed every time I had to go up a hill, then went back to steady.

Possibly a coil, which is on each plug. The blinking CEL indicates a engine misfire in 1 or more cylinders, when it is just on steady, it indicates an emission related code, which could be just a result of the misfire.
Hard to say which coil is bad, could be more than 1. They aren't cheap to replace at the dealer, not terribly hard to DIY if you search for instructions.
#43 of 76 1991 MPV Won't start and won't roll start
Jul 22, 2009 (11:59 am)
I bought a 1991 mpv with 140k miles on it. ran fine for about a week even took it on a 200 mile round trip with no issues. now will crank but not fire wo't roll start and when i try it All the indicator lights on the dash flash randomly and the engine sounds like it is running but the odometer is erratic to 1500 - 0 and back.
I am afraid of an ECU problem as I do not have alot of money to put into this car
any ideas of what i can look to fix to get er back to running and starting again?

Mechanic has just replaced all the sparkplug and no. 2 coil. he mentioned that the tester is indicating that no2 coil is defective, so he replaced it, however the problem is still there, he then told me two days later that I have to replace all the coil. I felt that this mechanic is guessing but I don't want to tell him directly... so I need any advise or assistance otherwise I will be spending more than 1, 000.00 ( non refundable) to replace all the coil as per his diagnosis. any assistance will be greatly appreciated.

You can buy a 6 pack of MPV coils on ebay for between $120-185 shipped and you should shop around with differnt mechanics to see how much they charge for the labor, I know the back 3 can be tricky, you could also doing it yourself there is a great article on replacing them on the Mazda MPV forum.

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?

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.

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.
