1986 was the year
5.0 was the ride
Now in 2018. The idle is surging
Stock 86 AOD mustang
Sometimes it don’t want to start cold. Then does.
Idles ok then surges and dies.
Sometimes it idles ok for 10min then starts surging and will die
TPS was @.007
Set it to .98/.99
Idled fine for 5-10 min then started surging again
Pulled iac, looked clean, sprayed it out anyway. Pulled the end off. Plunger was not stuck.
Ohm across the iac was 9.1.... I read that’s good
Each tab to the body should be 10k ohm but I’m getting OL
I read that is ok too
What’s next???
I have battery disconnected now, going to “reset” the idle rpm
