No idle........Sometimes

[crapmanche4l]

87 4.0l when it warms up (and when cold) you drive and come to a stop the rpm's go way low and lot of times dies. Also just when your going and just push in the clutch, so you have to three foot it for a minute after you stop to keep it going and then will be fine and idle till you stop the next time. So question is, censor problem? fuel system problem? I dont know, just seeing if its common or not

TPS or IAC probably.

 

[crapmanche4l]

where is the IAC?

 

[Fuller]

idle air controll motor

you can take it out of the throttle body and clean it but it probably needs replaced

where is the IAC?

Front side of the throttle body...
