Hello and thank you for using Just Answer

I'm Paul and I will help you with your Question

 

excessive smoking is almost always a bad injector on these vehicles

 

you need to have the injectors tested this requires a compatible scan tool and would run around 100 for the test

I have been told to put a quart of ATF in a tank of fuel. Do you think that would help?
Expert:  Paul M ASE Master replied 6 years ago.

It's possible that would help if you have an injector sticking.

 

I have not tried that personally.

 

I do know there are a lot of issues with the injectors on these engines.

 

I would say give it a shot and if it doesnt help have the cylinders checked out as described in the procedure I attached
