Ok so I have a 4 1/2 yr. old male pit. He's

SOURCE: 94 Honda Ex Will not start Where is the Fuel Pump Fuse?

it is sometimes located on the engine bay or interior fuse box just check the labels.., or you can try turning your car on but dont start the engine try to check on the back portion or near the tank if you can hear the fuel pump. Failure or low pressure fuel pump will stall you engine.

SOURCE: A/C sporadic compressor. Bypassed

i think that the problem is your A/C needs more freon134a it seems that when it has run for sometime the pressure gets too low and cuts out the LP switch

SOURCE: 2.0l alfa 156 bad idle try every thing change 4

Change the idle air control valve.That seems to be your problem.The only other thing it may be is your air temp switch located on the air intake.

SOURCE: lights on dash stay on and ac/heat fan does not work.

Your Ignition switch is not feeding 12 volts to the orange wire it feeds the accesory circuit. mine was melting poor design..

SOURCE: My Cadillac deville keeps popping codes p0171 and

You don't have MAF codes

Are you not aware you start with & diagnose
& resolved all code related issues first?

I don't see how you could change a MAF as you
won't know how to test it

PO-171 System too lean (Bank 1)
PO -174 System too lean (Bank 2)

That sounds like a vacuum leak that effects
both sides of motor

The front O2 Sensors get replaced at 100,000 miles

If that was done don't do them again unless they fail

80% of O2 Codes are vacuum leaks that lean out
the fuel mix. The Sensors are just reporting what they
see. It is up to a mechanic to find out why

When they report lean then the ecm adds fuel by
increasing injector pulse width thus bad gas mileage

I suggest buying a $50.00 code reader & study OBD2
Systems on the internet.
