That is called the throttle body.Probably didn't get it sealed back up causing a vacuum leak, causing high idle.

Heard loud backfire and found box ( part F 202 90 001 and 002)attached to air intake hose shattered . what is plastic box called and where is best place to get another. After it broke I could start car...

No problem driving it, but expect it to idle weird. That box is not really a neccesity, only to regulate the air coming into the intake. Now your not gonna be able to get that box at an auto parts store. Your best bet is to find a auto salvage yard, find a mazda: 626 dx,lx; MX-6 non-turbo or Ford Probe non-turbo model (year is 88-92). Just as long as it has that Ford 2.2 liter inline 4, your fine. Bring a 3/8's wrench with a 6 inch extension and a 10 mm socket, possibly a 1/2 and 12 mm, i can't remeber exactly. Also bring a phillips screwdriver and a pair of needle nose pliers. Remove the intake box and air mass meter and place them off to the side, DO NOT REMOVE THE AIR MASS METER ELECTRICAL CONNECTION. remove the mounting bolts off the box, carefully pull the intake hose and box out of the engine bay. and repeat the steps in reverse to install into your car. If you pull the part your self you'll probably pay less than 30 dollars (us). if you have them pull it, expect to pay more.

How to change a starter on a 96 mazda 626 ?

Write down the radio's activation code prior to disconnecting the battery' s negative terminal.

Remove the air-intake duct and the air filter housing. (assuming this your car is 4-cylinder)
Remove the bracket that runs between the inlet manifold and the starter-motor.
The starter-motor is by the left-side of the transmission over the axle-shaft.
Disconnect its solenoid wire and the positive wire attached to the starter-motor.
Remove the three 14mm bolts holding it up.
Once taken out, exchange it for a rebuilt one at your local autoparts store.
Installation is reverse of removal.

I cant find the air intake temperature sensor

on some cars this sensor is located on the air box where your air filter is or on the tube that goes from your air box to the engine

Idle s 2300rpm when cold, then revs between 1500-2000, while..

maybe vacuum leak or intake manifold leak. sounds like components are doing there job adjusting to air intake, matching the amount of air brought in with the amount of fuel that it would demand to produce correct emmission quality. check this out. you can use carb cleaner to spray around your throttlebody and intake manifold and if the engine idle fluxuates you have a leak.

91 mazda 626 erractic idle surge when engine is cold

My '91 626 did the same thing. I tested the throttle position sensor, and it was good so that wasn't it. The other likely culprit is the Idle Speed Control valve, or Idle Air Control valve, which is a $500 part new (more than I paid for the whole car). I pulled one off a 626 at the salvage yard and got it for 3 bucks, put it on (it's an easy DIY, just 4 philips screws holding it to the intake manifold), however I can't be sure that solved the problem, since I haven't run the car much since then. It would seem the most likely cause, tho, and a cheap fix if you go used. Other possibilities: O2 sensor or Mass Air Flow sensor?

The upper radiator hose runs into the thermostat housing. Remove the front of the housing and you will find the thermostat.

Change radiator

its fairly simple. First open pet **** valve on bottom of radiator (if applicable) to drain fluid then remove upper and lower hoses and disconnect and unbolt electric fans, then disconnect water temperature sensor (if applicable) and automatic transmission lines (if applicable) and remove fans with 10 mm socket, then unbolt top radiator bolts with 10 mm socket, simply pull up radiator carefully, you may have to remove part of you air intake system if above radiator if so remove clamp and 10 mm bolts holding it and pull up and away from air intake box after that it should be fairly easy to pull also always check your radiator cap for wear and replace it that may save you alot of money.
