99 f150 surging idle
I have 99 f150 w the 4.6 and 5spd manual. I just bought the truck and am going threw the little problems the truck currently has. on start up idle is good, where is supposed to be, around 7, 800. When driving the motor will surge as much as 1200 rpms between shifts then gently settle down to normal but somtimes u have to just shut it off then restart. The IAC tested below spec so I replaced it and problem is still there. What should my next move be??
Hope im posting this in the correct spot...Thanks in advance for any help.
