I decided that I needed to clean out my injectors because I don't know the history of my car other than my injectors are stock. I had a little bit of a rough idle and my buddy told me they used some BG products where he use to work, I told him I knew about BG and if you could not get BG stuff you could substitute with Seafoam...so I did. Well I took off a vacuum line on the intake and stuck it in the in the can...holy crap does this car have some vacuum! Half the damn can like that! Well I let the car sit for 30 minutes with the engine off and then drove the car a few miles, I had to laugh when the white smoke started pouring out and I could see people swervin...LOL I can imagine what I must have looked like smiling and laughing as I drove by people with my 1982 280zx with an exhaust leak and a thick white cloud of smoke behind me. After the Seafoam worked its way out and cleared up I took it home and let it sit for a while before driving again. Once it started back up the idle was noticeably smoother and felt a hair better on the pedal. It has been two weeks and no ill effects from it, in fact it is all good and still smooth. Give it a shot.

 

I'm not a gimmick fanatic but Seafoam is no gimmick. Awesome stuff. A good general tip for Zers (& I'm not trying at all to say you did it wrong thxone) using it is to introduce the stuff before the tb so it will clean that too, plus get well distributed cyl to cyl.
