Light grey smoke

Hi Everyone, I'm getting lots of light grey smoke from my exhaust. What should I do to solve this problem? Any help will be appreciated. Thanks

Thanks bigblackdmaxx. I had a feeling it would be an injector issue. Does anyone know of someone in the Los Angeles area that can check my injector rates? The help would be appreciated. I also did the ice pick trick today and checked my harness it didn't help. I'm still smoking like a CHOO-CHOO!

sounds like injectors, too much fuel or not enough air would make it black as night, like collant entering the cylinder would make it grey

Not smoking at all when at idle, but when i put it in drive and push the accelerator 10% it starts smoking and doesn't stop unless i release the pedal.
