Is check engine light on?
Any codes? you can pull codes using cruise switches if you don't know how let me know
Use the following procedure to retrieve the flash codes from the check engine light:Turn the ignition key switch to the On position/ Engine OFF.Turn the cruise control ON/OFF switch to the OFF position.Move the SET/RESUME switch to either position. Hold that position until the yellow lamp begins to flash.The yellow lamp will flash in order to indicate a three digit flash code and the SET/RESUME switch may be released. The sequence of flashes represents the system diagnostic message. Count the first sequence of flashes in order to determine the first digit of the flash code. After a two second pause, the second sequence of flashes will identify the second digit of the flash code, then the thirdAny additional flash codes will follow after a longer pause. It will keep repeating codes until you turn off key.Any questions just let me know.
Thanks for info Gary,
This sounds like you may have a cracked injector tip then,
pull valve covers and short out each injector by putting a chisel between rocker arm and housing to hold injector down, when you get to a bad injector smoke should go away, you can also use a 6-12" extension and socket on rocker arm to hold down, just be careful around wiring
With a cracked tip disconnecting wiring on injectors won't have any affect on sound
Please take the time to reply/Rate me with stars at top of page so I get credit from the site for my time..Thank You!.
Are those the same injectors you disconnected to test each cylinder? if so that is why they are logged codes
Check the injector wiring harness where it goes through rocker housing that is a known problem area
also check under valve cover harness for chafing
If a lot of water went through this fuel system the injectors are junk
I still think you have a bad injector
to confirm a injector issue pull exhaust manifold to see what injector is blowing all that smoke
you need to replace injectors
