Idle problems

[jeff1414]

everytime I come to stop my idle gets ruff and drops a little bit. I replaced my iac a month ago along with a new k&n. And it still does it. My rpms don't drop as low now but it seems like my idle is a little ruffer. Is there anything else I can do to fix that problem or just forget it

I think what youre describing is normal, mine does it, always has. How low does it actually drop?

Time for Idle adjustment. I shall send you to this Mustangworld.com throttle body article.

sometimes it won't do it. Then some times it will go down for 1/2 second and other times a whole second. But every time I stop it always is idling ruff like the idle is to low or something i don't know what to do and it just runs slugglish

i have to change the tb. I don't know about that. I won't think that would be the problem. or can you adjust the idle on the tb

try cleaning out the MAF sensor. it could be dirty. that'll definatly cause random dipping in idle, it happened to me. try some dielectric cleaner on it (if u can actually remove the torx screws and brush the dirt/oil off the 2 wires then whats more effective). hope this helps
