Weird stalling while decelerating/ idling prob

[mrayburn1188]

Ill be driving my car and when i decelerate the rpms drop all the way and the car bogs out and stalls. Most of the lights come on on the dash as if the key was turned over right before the car was actually on. It only does its decelerating. Also my cars idle will drop up and down when i start the car then it will stall. One time i was under the car while the car was idling weird and i pressed in the maf sensor with my finger tighter even though it didnt seem loose and it seemed to help for a little bit. Does anyone have any idea? Thanks a lot. Ohh and also i have a 92 s13 hatchback with a ka24de. Thanks for your help

could be TB/ TPS or ur MAF from wut ur sayin...

sounds like ur not getting prower air flow...

im leaning more towards ur TB, seems if ur deceleration...it closes off the butterfly to much... or it could be ur TPS

i just had the same exact problem in my s14. problems solved though, for one, i did have to relocate the maf. secondly there is a black hose right in front of your intake manifold, i forget what it is for, but check for a kink in any black hose around that area, that would have a lot to do with, post or call me at 757 714 4127, you have any questions.

my car is doing the excat same thing right now. 1995 s14 240sx. happens when im slowing down and when im just sitting at a light. it drops down to about 500-250 and then tries to rev itself back up to normal rpms but stalls afterward. i had a problem before when it would jump on rpms when i was driving and i thing its came back. i hope i dont have to dump the same amout of money as i did before. because it was high.

oh and another problem, that can cause all yall's problems. If you have recently put in a lightweight flywheel . or newer stage clutch in, that can also have a lot to do with it.

na i have an automatic stock 240. so im guessing it has to be the MAF. still havent been able to try anything.
