AGAIN NARROW VS WIDE, KEEP IN MIND MY BIE HAS LIKE ONLY 4K MILES, BOTH O2 SENSERS WERE CLOGGED REALLY GOOD, SO IF ANYONES using tuners, you might want to change them out, even if you don't have a tuner, the ecm cannot possibly get a accurate reading from them, this pic was after cleaning with denatured alcohol and other chemise, as I have friends w /rockers and if worked, was gonna pass this TIP on to them, like I am to anyone here, see when I do a build thread, its not just look at me,
