Reset throttle stop on mazda 3
Well, to get it in gear, you can do a few things. The first being press
the clutch in and run it through all of the gears without applying
throttle and then try reverse again. You can also let off the clutch
half way and slightly pull the shifter in to reverse. As you let off,
it'll eventually pop right in to gear.

This is easily
done … all you need is a piece of wire (like a straightened glider clip) and a
the engine with the bonnet up you will see a little black box on the top of the
passenger side wheel arch, with the words "DIAGNOSIS" embossed on it.
Open it up by pushing on the top of the side clip. There will be a number of
cells inside, some with terminal points. The lid of the box contains the key to
these cells. When you insert one end of your wire into the TEN cell and the other in the GND cell, it causes the ECU to be
bypassed and the ambient idle setting will be used.
black air intake tube which runs in front of the engine block to where it meets
the intake plenum on the driver's side of the engine - that’s the throttle
body. On the top left side of the throttle body you will see a small raised
cylindrical section, sometimes with a black plastic covering, which contains a
large Phillips head-topped screw. This is the idle adjustment screw. It turns
anti-clockwise to increase the ambient idle speed.
So now here is the procedure.
1) Make sure that the engine is warm, but not hot.
2) Turn off all electrical items (fan, radio and lights)
3) Start the car and after it settles into a regular idle notice where the
needle is on the tachometer. It should be just over the graduation mark below
the "1". (around 850/900 rpm)
4) Bridge the TEN and GND cells
5) You should notice the idle speed change after a few seconds.
6) Have a look at the tachometer. If the ambient idle speed moved then you have
discovered the problem.
7) Slowly turn the idle screw until the revs come up to just over the graduation
mark on the tachometer.
8) Do this slowly, as there is a slight lag in screwing and response.
9) If the radiator fans come on during the process then stop adjusting and wait
for it to go off.
10) When you have it idling where you think it should be remove the bridging
wire. In a few seconds the ECU idle setting will kick in. If the engine remains
at the same rpm then you have matched the ambient idle to the ECU setting.
11) If not, then replace the bridge and adjust the idle screw,
12) Repeat steps 10 and 11 until the idle speeds are matched.
