I have a 2000 V6 3800 series camaro and my service engine light was on and i went to go get it scanned and what came up is cylinder 5 failure i got that fixed and a fuel injector failure also came up, when i step on the gas my car hesitates to go, when it idles the exhaust putters/pulses. And when i accelerate i get a very heavy exhaust/gasoline smell coming from my A/C. any idea on what fuel injector it could be, or any possible smaller problems??

 

What was the code for the injector??? What was done about the cyl 5 misfire???

 

A fuel injector problem could definitely lead to a de-pressurized fuel system, which in turn could lead to the sputtering. It could also be a pump error as well. How did you fix the 5th cylinder? Was it a misfire? Your A/C system is directly correlated with your vacuum system. If you have a vacuum leak in turn with an exhaust leak, it could lead to exhaust fumes(carbon monoxide) inside the cabin. It isn't something that should be taken lightly as it can cause light headedness and nausea. I would replace the injector and use seafoam in the brake booster line to pinpoint any existing leaks
