Injector clogged running to rich 99 Trans Am its not running like it should, fuel is way to rich very strong and think it an injector clogged. I have ran 5 gallons on AV Gas through it and no help. Any suggestions? And would it be better to pull each injector out and see which is spraying correctly or not. Any help would be appreciated

Thats what you would think, but you can be behind the car and the fumes are so strong its running really rich. What do you think it might be?? Maybe resetting the CPU might help? Its normally runs 12's in 1/4 mile and its running slow 15's and a lot of fuel is coming out of the exhaust. Smells like an old car that hadn't been ran in years.

Well if it's running pig-rich it sure as heck is NOT from a clogged injector! One that is flowing too much for whatever reason, but NOT a clog, which would limit flow.
Check your O2 sensors and MAF if you have one. Something is out of whack somewhere.

I have checked the 02 sensors and started pulling the spark plugs out and 2 of them on drivers side Is black with carbon like stuff on them and the rest of them look kinda wet looking. Going to replace them does anyone think that this will solve the problem or what else do I need to check. Thanks for the comments and suggestions. Any will be helpful
