ive got an off road h with the smog pump pulled out. ive been putting off emmissions for a while but i have to do it. by the way, i already failed pretty bad the first time with my stock catted pipe. i was thinking to retard the timing, clean out the tb, and give it some alcohol. also what i wanted to do was put on my catted pipe and drill a few holes in it so the hoses dont pick up the fumes. think this might work? the dont look underneath at all
