I do this every season just to keep everything happy. If you don't know they last time your TB was calibrated, it's a good chance that it's due. Now if this doesn't help, then you have underlying conditions as stated.
V6 Auto owners, Do this NOW! Lag, Hesitation, Abrupt shifts (FIXED)
Does your 6 suffer from:
Passing gear lag, takes it sweet time to drop a gear and accelerate
Abrupt downshift (skipping gears like 3->1, 4->2, 6->3)
Jerking off idle while rolling on and off the throttle i.e. traffic jams
Abrupt engagement under light throttle
Non-linear control of engine speed for minor throttle changes
I've owned my 6 for just about a year now and have a VERY SIMPLE CURE for these conditions. Reset the Throttle Curve! Original is here: http://forum.mazda6club.com/3-0l-v6/...fts-fixed.html
HOW TO RESET THROTTLE CURVE:
Drive car to warm engine and drive train
Stop car and leave transmission in Park (Manual trans, leave it in gear).
Turn Ignition Switch OFF
Let off throttle pedal completely
Turn Ignition Switch on to Run position BUT DO NOT START!!
Slowly, consistently and at the even rate, depress the throttle pedal completely to the floor. BE SMOOTH!!!
Once down completely, Slowly, consistently and at the same rate, RELEASE the throttle pedal completely from the floor.
Once at the top, remove your foot and turn the Ignition Key OFF!
- Repeat every 90 days or when you notice it not playing nice!!
As you all know the servo sounding noise under the hood when the key is turned off is the Throttle Body Calibrating itself for idle and partial throttle load. Over time, most of us NEVER use full throttle as much as we use idle and partial throttle. This is my theory but it seems as if the ECM looses track of the linear curve from idle to WOT and makes decisions based upon a non-linear curve. This simple process has corrected my car making it so much more pleasant to drive. Doing this every 3 months is now a MUST!!
I've done this to several TBW vehicles, Toyota, Nissan, Ford, and Mazda 3. It seems to help all of them. Give it a try and report back.
Results may vary but it works well on this combination: 2006, AJ 3.0 & AW6A-EL 6 Spd
THIS DOES NOT FIX; stumble, misfire, CEL Faults, poor tune.
TAG: Throttle By Wire, LAG, Abrupt engagement, being a Jerk!
