Sounds like the throttle body is sticking. Get under the hood and have someone rev the car and see if you can get it to happen. A little WD-40 or other lubricating spray should provide a temporary fix.

It starts, but why won't it idle?


It sounds as a bad idle contro motor. Locate idle control motor, usually at throttle body. Tap on it a couple of times and see if issue resolves.

I get a whistling noise i think is coming from throttle body


Your whistling is quite possibly a vacuumn hose leak on the passenger's side, top of the engine. Look closely at the hose connections coming from the PCV. Small holes can develop in these vacuum line connections, and you will experience a rough idle, as well as the "whistling" noises.

When car picks up speed the heat blows. when u stop or slow down. cold air blows


Tell me when you speed up is the heater set on hot and high speed?????
WHEN you slow down is the fan still going at the same speed or dose it go very slow when on idle.
If the Fan stays on high but runs cold when going about 80 in top but when you speed up it gets hot and then back off slightly then its sounds like Water pump isent pumping the water around the engine correctly ,but then it should make the engine run overheated.or it could be a slipping fanbelt, but then that should make the Alternator to make a noise,so {throttle to 2000 rpm from idle standind still} and see if there's a noise coming from the water pump area.
The belt should have just a little free movement more on the longest part of the belt(a very little about 1/8' movement
So check it out and let ne know how you get on .

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.



Comment by mohammed387, posted on Oct 05, 2008The solution is to reset the ambient idle setting
This is easily done … all you need is a piece of wire (like a straightened glider clip) and a screwdriver.

When facing 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.

Follow the 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.
