Guys--I need your help. I have a 2002 Millenia with the 2.5 liter. Only 35k miles. Upon acceleration there is a very slight shutter or jerking feeling. You can definitely feel it but it is very subtle. No codes. Happens when warmed up and cold but more pronounced, but still subtle, when warmed up. Noticeable between 2-3k rpm. Happens with and without air conditioning running. Any help is most appreciated. Thank you.

 

Does it only do thwhis while driving?

 

It is only upon acceleration. Thanks in advance.

 

So it dosen't sputter in park, I'd suspect transmission.

 

Clean your Air flow meter.

 

Well it turns out it was the axels. I had them replaced with napa parts and it turns out the car is very sensitive and only the axels from the original manufacturer work well.

 

that's bull. we have 2 99's, and i have replaced the axles on both cars, both sides, more than once, with a variety of aftermarket brands. i have NEVER used an oem axle. the very first axle i replaced was by cardone, and a very good friend of mine, who is the parts manager at a mazda dealer, said at the time, cardone remaned the axles for mazda usa, and they used cardone from local parts suppliers. that has since changed. i now use the oreilly auto chinese made new axles, simply because when they go, and they will, i can have a new one that day for free.
