2003 7.3 erratic idle
Not my truck, but here is what it is.
2003 F350 Dually Lifted on 35's, 7.3, Auto, 40,000 miles.
On cold starts, idle will go up to almost 2,000 rpm's then drops to around 100 where it will almost shut off. Will do the same thing when put in drive and when accelerating will fall on its face after you let off it'll regain rpm's and then take off normally. Once it's warmed up no effects, even if restarted after sitting for an hour.
This is the best I know, no codes yet and I'll try to get a video tomorrow or something. Any ideas? It's kinda vague I know, but I'll get more info when I experience it first hand tomorrow.
