1996 MAZDA PROTEGE DX, 1.5L 5 spd., 110500 miles. This car is now sold and unfortunately I've a new problem one!

Problems:
The check engine light goes and stays on.
I took it to CheckerAuto and their machine said the problem was: EGR booster sensor. An acquaintance pulled the clip out of the sensor, removed its hose, blew into it and put it back together. This made the light stay off for about 2 hours.

[-- Also there is a high pitched squeak when I turn the car wheels. It seems to be in the front. What might that be?

-- If the squeak is the brakes, does that mean pads or pads, rotors and calipers? I bought the car used and don't know how old the breaks are.

-- the AC blows, but is faintly cool. I had a can of the new type Freon put in it . It helped a little but not as I had hoped. Is my AC going bad? What causes this behavior?

I do have an acquaintance that can do some simple things for a car.

First thing is to get a chilton guide for the car.

Won't comment onthe EGR.

E) Is the car standing still? or rolling when this happens? Are you using the brakes when you hear this noise?

F) Not fair to diagnose brake problems over the internet. Go to a brake shop and have them do an inspection.

G) Try cleaning the rad and heater core. The car is old enough that they may be plugged up somewhat limiting the air flow.
