There is only one oxygen(02)sensor on this car.it is located in the front exhaust pipe,it measures the amount of oxygen in the exhaust so the computer can change the amount of injector on time for fuel control.it is a single wire sensor that is threaded in the pipe.

93 sunbird code 44


Code 44 is a "lean exhaust" code. This can be caused by a bad Oxygen sensor, vacuum leaks, badly misfiring cylinders, holes in the exhaust, etc. However, if you do not have the knowledge or equipment available to properly diagnose this condition, I would recommend replacing the O2 sensor to see if that take care of the problem. If the code comes back, then you will probably need professional help.

Fuel smell rough run when started


That condition is a fire hazard condition, I recommend towing to a good mechanic, as any errors increase fire hazard.

What needs to happen is to locate EXACTLY where the fuel is coming from, then why. Sometimes seals, sometimes stuck injector, sometimes computer invoking based on something.

I would expect that you have a check engine light on, if you do not, that may point you to external leaks only, and not leaking injectors, but check everywhere to that point. Fuel leaves stains, so it should be easy to find. No smoking, and use LED lights and lower explosion and/or fire possibility.

If you do have check engine light, pull the codes and follow from there, but remember, a leaking injector may manifest as oxygen sensor issue, when raw fuel on it is the issue, sensor a victum. the codes are a clue, not the answer.

Pontiac sunbird 1993 2.0l that has a anti freeze leak from the hose at the bottom of the engine ,the one closest to the fire wall it is on the right side


This could be from the hose that goes from your engine to your heater. I don't know the layout of the sunbird but if you are sure that it is antifreeze that's what it should be. You'll need to get another hose and replace the bad one. Good luck!

Where is the oxygen sensor


It's on the rear exhaust manifold. You will need a oxygen sensor socket to remove it. If you are not saving it & tend to replace it, snip wires & use a normal socket. Saves the price of the special socket! Good luck!
