rough idle/gas smell HELP!!!!!
Within 10 mins of driving this morning my car began to run really rough as I shifted into second. It sounded like it was misfiring. Once parked it ran horrible and had a very rich smell of gas. One whole side, drivers side, bank 2 I think, isn't working. I could still hear the misfire. What in the world is wrong! !!!

Sorry for late reply, been busy. My mechanic said its throwing like 12 codes and he's trying to figure out is the right one causing everything else to trip. Only thing after market is a CAI and diablo sport tuner. Off road h pipe and flowmasters. The problem happend outta no where with no signs. It just immiediatly began to shake and idle hard and pop sounds from the exhaust. I cld smell rich fuel which I'm assuming is causing a backfire. Unplugging all the injectors on one bank didn't do anything unlike when u do the same to the bank which is working. It seemed like I'm getting spark and fuel but I can't say that 100% All I can do is wait now cuz my car is at his shop. Could it be electrical or possibly bad ignition coil? I'm clueless

It could be a bad coil, it would smell rich, because that cylinder is not firing. Data log your fuel trims and you'll know for sure which bank, because that 02 sensor will see more oxygen(from lack of combustion) and add more fuel.
