ok ,back b4 the tranny blew on me i had a huge issue with gas ,ended up beeing the regulator dumping gas directly in my intake badly ,so 3 oil changes later and ALOT of gas out of the tail pipe litterally its sounds funny and ive lost some low end snap.i was easily hitting it at 30-40 mph and roasting the 20s right off it ,now its not doing so good.i changed the plugs several times and today and they looked perfect today but i changed them any way and gapped at .32 .i do usually gap at .35 except the last 2 times .maybe thats an issue idk if that can cause that much power loss.anyway my exhaust doesnt sound right it sounds muffled at light acceleration,wide open sounds the same as usual.ive read alot about aftermarket high flow cats going bad quik .i was wondering if the gas issue could of ruined them quicker.im not talking alittle gas im talking gallons.it took 2 days to clear it up.any sugg guys ,seems like the only 2 things that i did at the time frame.changed plugs because of gas problem.ive always ran 35 tho on the plugs until then also.im more concerned about the converters .boy ive missed this for the last 3 weeks .lol.thanks again for opinions.
