#7 of 17 Cold Acceleration by dr_who May 21, 2008 (6:50 am)
I have a 2007 Mazda 5 GT 5 speed manual (that, in general, I am very happy with) and have experienced the engine stumble mentioned in this forum. It is on my to-do list to go get the issue addressed.   I have also experienced cold acceleration issues that may be unrelated to the engine stumble TSB. It feels to me like I am driving a carbureted car instead of a fuel-injected car for about the first five minutes after starting the car when the engine is not hot. Acceleration is rough and slow at low RPMs and then abruptly kicks in smoother and more powerful (feels like a turbo kicking in after winding up) at around ~3000 RPM. This is a problem in both winter and summer driving. Once the engine is warmed up, the acceleration problem goes away.   Has anyone else experienced these cold acceleration issues? Is there a known fix? Does having the engine stumble TSB fix (reprogramming the PCM) done on the car also fix this issue?   Thanks for your help.

Replying to: dr_who (May 21, 2008 6:50 am) I own a 2006 and a 2008 and I have felt the weird accel while cold in the 2006. I'm sure the latest TSB that updates the PCM will fix it. I say this because the 2008 does not have it (although basically it is the same car). I have not taken them for service, but will do in the next opp.

Replying to: whobodym (Apr 12, 2008 8:23 am) to update you all on my experience, 6 weeks after having had the Feb 2008 Mazda SB work done to our 2006 5 Touring 5MT -- I remain completely satisfied that the service bulletin solves our previous problems. To be clearer about other guys' discussions of cold-start behavior, I live and drive in the USA Pacific Northwest, essentially at sea level almost all of the time. Our winter time low temperatures are typically no colder than 35-40F ( 0 to +5 celsius ). I have never ever started and driven our 5 after being parked overnight, any colder than 25-30F (-5 to -1 celsius). If some of the commenters are talking about the behavior of their cars in conditions much colder than what I'm talking about, that would be conditions I have no idea how our car would have behaved in, prior to the SB. I wouldn't be surprised at all if the SB changes engine behavior for the better, in extreme cold conditions. But I have no such experience myself. Remember of course, the SB is zero cost, and takes almost no time to install. Just go do it!! Replies to this message: mchow (Jul 24, 2008 5:17 pm) coolmazda5 (Jul 24, 2008 6:34 pm)
#10 of 17 Is this engine stumble or Turbo Kicking In by randyuk Jun 12, 2008 (12:40 pm)
I have a UK spec Mazda 5 '07 model bought from new.   When driving around 60mph a shudder happens and a sort-of feeling of a very temporary loss of power, almost as if it is being held at that speed for a second despite trying to accelerate.   Is this just like the engine stumble or could it be the Turbo kicking in??   The car is going in for a service recall tomorrow, so could someone offer an opinion rather quick, please.   Thanks.

Replying to: randyuk (Jun 12, 2008 12:40 pm) I'm not sure how to answer your question fully. But I am pretty sure about a few things. All USA model Mazda5s use the MZR 2.3 liter 16 valve gasoline engine, which I suspect is not available at all outside N America. Our USA engine has variable valve timing. The 1.8l and 2.0l engines for other continents are not available in USA, nor is any diesel powered Mazda. (This may change with $4/gallon fuel, but that will take another year or three.) I am quite sure that the only turbocharged Mazda5s anywhere in the world are the diesels. So if you are talking about your car being a diesel, there can't conceiveably be any connection at all between the USA 2.3L gasoline engine stumble, and your car. If you have a 1.8L or 2.0L gasoline powered Mazda5, your engine I believe is rather similar to the USA 2.3L model and I am 99% sure you do not have a turbocharger so that's not the problem, but there could be any number of other little differences in all manner of engine hardware and software and it's impossible for me to know whether EU gasoline engine Mazdas have the same problem I experienced. Yes, my car used to have a shudder and a feeling of delay or hesitation when applying a medium amount of throttle, from a state of coasting or very light throttle. The key in my case was engine RPM being in about the 2000-2500 rpm range, not the vehicle speed. A severe stumble (head-jerking) occurred only very rarely, say, once every few months, but a much more subtle feeling of delayed throttle response, happened all the time but I doubt many drivers would notice it at all. By all means, bring up this question in your service appointment. But notice that my problem existed pretty much unchanged and unresolved, for more than 2 years after the Mazda5 was introduced in the USA. Mazda may be trying to invent something applicable to your car too, but it doesn't mean that they are sure to be finished yet. Replies to this message: randyuk (Jun 12, 2008 10:33 pm)

Replying to: whobodym (Jun 12, 2008 4:36 pm) Thanks for that. Neglected to mention is a TurboDiesel. And, yes, there is no way anyone could miss this shudder - even my wife found it quite obvious.   The dealer here in North London has made several attempts to fix a problem I have been having with the rear parking sensors - all to no avail - so are trying another attempt at fix, today. I fear I am in danger of becoming a "serial complainer" - but this is the first new car (demo with less than 1k on clock) and there have been several things that I have been unhappy with. Most were addressed quickly.   But get this one - took the car in for its first service recently to be presented with a bill for nearly £1000.00!!!! All the tyres were bald or near bald - ther service manager told me the alignment was wrong at the time of production (and Mazda clearly knew this) and were offering to fix the alignment for free and a "contribution" towards new tyres - very generous!!!!! I got £200.00 back but still had to pay a huge sum that I was in no way counting on.   Ever heard ot this in N.A.????

Replying to: whobodym (May 24, 2008 9:19 am) Hi,   I live in Toronto Canada, so far I am very happy with my 5, except for the engine stumble. There are more and more Mazda 5 on the road nowadys.   I have a 06 Mazda5 GT Manual, and I just went to a local dealer to explain to them the situation. I brought along the TSB#01-008/08, insist to update the PCM. The service guy is ok and finally update the latest PCM. But the code is F0010XFX.3. I do not really know what the code is, but since he told me the PCM code is updated, I hope the problem is gone. Does anyone know if this is the right code?   Since I brought the car to another dealer earlier this year, but was told that there was no update to the onboard computer, and now there is an update. Hope this update can cure the issue. Will keep update to post if it really work. Replies to this message: coolmazda5 (Jul 24, 2008 6:34 pm)

Replying to: mchow (Jul 24, 2008 5:17 pm) , just reprogrammed today as well. Never had the problem but it can of accelerates more uniformly. I hope it also improves gas mileage at least a little. The service sheet indicates the TSB number correctly 01-008/08   I own a 2006 and a 2008 Mazda5s (US, Sport, 5MT)
