Need Help! 1990 Mustang GT
I can't get it to pass DE inspection. It fails low idle test only, I have replaced everything in the ignition system except the ignition box. Also replaced O2 sensors with OEM ones straight from Ford. It started smoking on start up now too, did a compression test and all cylinders read from 126-135. Also replaced PVC valve and mesh screen that sits under it. Any help would be greatly appreciated
