Cylinder 6 Fuel Injector
 

I had my 02 3.8l monte diagonosed with a bad fuel injector on cylinder 6. I have the fuel injector but can't locate which one to replace for the 6th cylinder. Also the car has been shifting hard and the mechanic wanted to replace the throtle body on my transmission for about 1200 but I'm hoping once the engine is running right it will fix that problem.
