Head gasket or waterpump or thermostat check thermostat first!

Look for that on the air filter housing, where GM usually puts it. 2 wire connector to it, measuring intake air temp., it has to be in the air stream going into the engine.

is under the dash on the left side of the steering wheel

yes.. or final drive seals..put it up on a lift or take to rapidlube where you can get under it for a look...

It is behind the motor, but if you are getting a code, keep in mind that a knock sensor does it's job... sometimes the senor is picking up noise from the timing chain being wore and slapping

Put new coolant sender in.

It is a bit odd to get the same low compression in 2 cylinders so far apart. Are you sure you are measuring the compression at those 1 and 4 cylinders properly. Confirm you are following the right procedure for measuring the compression. If you have got the right readings then you likely have a head problem because rings tend not to go bad like that at the same time. Could be a warped head or valve issues. You might be noticing pressure related issues in the crankcase or poor running due to the pressure bypassing the exhaust.

Did you use a genuine replacement sensor. I ask this because aftermarket sensors have different parameters (settings) to original and the cpu still thinks there is a fault

MASTER CYLINDER BAD, SLAVE CYLINDER BAD, OR CLUTCH DISC WEAR

look under back seat sometime there is actess if not go under car

take it to any parts store and they will scan it for free

MR OR MRS ADAMS,That is false information. The dipstick reads 2 (TWO) quarts.

look near the water pump for the coolant leak its just below the ac compressor the shifting hard check for power to the pressure control solenoid on the trans

Probably. Assuming the check engine light is not on, if you changed the IAC it could take driving the car for the computer to get the valve in the right spot.

replace radiator/hoses, and instead of water, use anti freeze.

loosen your brakepipes at brakemastercylinder then tighten again if the car moves it could be that your mastercylinder is building presure needs to be overhalled or replace

remove your rad cap fill with water start your car if their is a lot of bubbels it could mean you get compression in the water maby the headbolts is loose or maybe the gasket is gone

If you feel that you've hit the hole that hard, you should have the wheel and suspension checked by a professional. The strut or control arm may be bent and in need of replacement, but that's only if you've really hammered it.

Find the cause of the check eng light and find the cause of the poor mileage.

It may not be a fuse issue. You could have a bad socket connection. Pull the wire from the back of the lighter socket to see if you have power there. If you do, then the socket is bad.
