2003 4.6 idle hangs up
2003 2wd f150 4.6 Triton
Idles high at first start up around 1500 to 2000 rpm for a couple minutes then smooths out, but while driving the rpm will hang up where it was for a couple seconds like cruise control is on, and if I slow down the idle fights me. I assumed it was the temo sensor but replaced with no change. Not throwing any codes after I changed the temp sensor.
My next step is to look for a vacume leak but with how its acting i dont think that's it, it is not constant at all it picks anc chooses when yo stay high in the rpm while driving, and it died in me once when I stopped fast and the idle stayed at about 1300 then died.
Any help would be greatly appreciated thank you.
