the other day i was driving and showing a friend of mine my nitrious. I go to use the nitriuous and i get a big backfire in my intake. I pull over to make sure everyhting is okay and my car is now reving from 1 to 3 grand by itself. There is somesort of vacuum problem, or could it be the sensor above the fuel filter??? i have checked all the vacuum lines and they're all okay but when i start my car it still revs from 1 to 3 grand..... help.

 

sounds like maybe you blew a gasket or a seal bro..showing off isnt worth blowing a motor..be careful

 

SOUNDS LIKE YOU BLEW THE TPS.

 

or u blew the idle air control valve

check for codes.... maybe that will tell u wahts meesed up
they usually jus tmake the car fluctuate from 1-2 k.....
but who knows.....
we might add ur case to the book : "amazing things that happen to hondas"
