I just got a 1995 Nissan 240sx and feel my car doesnt perform like it should. It feels sluggish. I changed the spark plugs and I got clean air filter. Everything is stock. The only thing I notice is that it feels like air is having trouble getting out of the exhaust. My car also rumbles slightly in idle. HELP! I need help to find out ways to restore perfomance to my car!

 

Do a FULL on tune up. Sounds like your exhaust might be clogged, maybe your cat. Try upgrading to a Z32 fuel filter

Oh yea, welcome
