Denatured vs. iso-propyl alcohol Smog ?

[90240sr]

Im trying to find out which one would be better for lowering NO number for smog. I have read about people using both with good results.

I have personally only hear of people using denatured. But then again, ive PERSONALLY never done this before...

why not use denatured? I know that what almost everyone uses that has done it...

[!Zar!]

Or just fix/clean the egr...

Thanks. I still gotta check the crammed vaccum hoses in the rear first. I calened out the egr system already but the car doesnt die or stumble when i push up on the egr from the bottom.

Make sure that the egr and bpt are not torn and working properly. Run denatured alcohol and get the the test done.

i use denatured alc every smog and my car pass like new car almost LOL

I do new plugs - sea foam - clean egr - fresh oil change with alc and my car pass all the time

If the EGR/BPT valve doesn't work, you won't pass.


Period.


Make it work.
