hey guys i was wonderign if this is bad or not i have a 94 camaro z28 a4 with not cat intake and exhust. now the problem is when i use nitrous and then i let off the gas my exhust backfires....now also when i dont use nitrous that car will back fire when i let off at high rpm. is there somethign wrong with my car?????

 

This is most likely because once you turn the nitrous off it evacuates the line between the solenoid and fogger immediatly but the fuel might take a few seconds to evacuate since its at a much lower pressure making your car run rich causing the back fire. If it's only right after you spray I wouldn't worry, if it's like an hour after then I'd start to worry.

 

sweet thx a lot for your help that just what i wanted to know =)

 

No prob, glad I could help.
