ok my 01 prelude just started to have a problem stayin runnin when im not givin it gas/it wont idle.....runs fine as long as im pressin the gas as soon as my rpms drop like below 1500 it putters out and stalls? wtf. lol not fun

 

check egr, iacv, and maybe try doing this http://92lude.com/idle_air_control_bypass_mod.htm. hope it helps man. gluck

 

sounds like a problem with the injectors or the IACV as MJ stated

 

ok so i was told including the stall problem the pingging from my motor could be a valve problem i ran the codes from the check engine light n ....4 of wich were miss fires....so i was told could be my valves wich is the noise n the stalling on low rpms so i take off the valve cover didnt see ne thing out the the ordanary i put the cover back on but dont bolt it down n its stays runnin bad o2 sensor...dude im lookin 4 ne thing
