my car will idle fine around 800 then when im driving and put my car in neutral and let off the gas the idle will go down to around 200 and sometimes the car will just stall out. What should i do, just raise the idle, or is there a bigger problem thats making it stall out. The car is a 94 gsr with 125,000..i just installed a fpr and the pressure is around 45. the head was also just rebuilt.. thank you for the help

why dont you adjust the idle screw in the throttle body, my idle was at 2k and i adjust it, and went to 900, its the one with the flat head screw.

 

i agree - same thing happened to my car, whenever I was at a stop, the idle would dip down really low, and sometimes die. I properly ( i say 'properly' cuz each adjustment method is different, not always just turning a screw) adjusted the idle screw, and it works great now!
