idle stumble gone

[havoxe30]

i had a bad idle stumble when i got the car did everything cleaned everything but just wouldnt go away
so i was doing a compression test today and the plugs looked semi old so hay just replace them so i bought some ngk plat plugs and started up fine didnt pay much attention and i was at a stop light and i noticed no stumble yaaa
so i guess i should of just for got all the fancy stuff (afm,icv,o2c ) and just stick to the basics with idle stumble, plugs ,plug wires

whell it worked for me at least

also dosent hesitate when you step on it

had the same problem. when you rev it up and then let off the gas does the whole car shake and the engine sound like its going to die? i replaced all my vacum hoses becuse the ywhere cracked and leaking and the problem went away. check the vacum hoses.
