I have a 2.2 non eco tech motor in a 1998 cavalier I have the NOS fogger nozzle right above the throttle body where the ninety degree bend is. Where should it go I had a Nitrous back fire I am thinking it is too close to the throttle body? I have plenty of fuel pressure and I have colder spark plugs can somebody please give me an opinion on where to put the nitrous fogger

The nozzle should be at least 8 inches away from the T/B. Check your plugs now.

my plugs are fine do u go from the ninety degree bend or from the straight intake is? i will put up some pix

What i did in my 2.4 was drilled a hole in the top of my filter and put the nozzle in that. I had great results. I have not had a bakfire yet.

i drilled a hole about six inches away from the tb on the intake, i dont think it matters that im running zex but thats what the instructions said. it works good.for me though.
