Hey guys, been a reader on here for years, just forgot my old login stuff so I made a new account.
Anyway, I’ve got a 95 454, NV4500. I bought the truck a few months back running but not driving. Had to rebuild the transmission and put a new clutch+flywheel on it. Been driving it for about a month now and it’s been real good to me. Slowly but surely fixing up the little dumb **** the previous owner did. He thought he was a mechanic, electrician, and based on the stupid ass stickers on the toolbox lid, a cowboy. LOL [emoji23]
As for my idle issue. It’s been this way since I got it running. The idle will hang up around 12-1400rpm but only while I’m moving. Doesn’t make a difference if the clutch is pressed or if it’s out in neutral, it does it. It’ll do it even when I’m JUST BARELY moving. As in I’m rolling up to a red light, I’m going so slow that I’m done downshifting so I’m in neutral. The idle will hang right up until I feel the little lurch of the truck fully stopping. As soon as I fully stop, the idle drops right down to about 800rpm with no hesitation. I’ve verified that there’s no vacuum leaks with the good old starting fluid around the sealing surfaces while the truck is idling. I’m thinking that maybe it’s supposed to do it for some reason or another. The only thing I haven’t done is unplug the speed sensor off the top of the transmission to verify that it’s 100% speed data related. Assuming that it’s supposed to do it, is there a way I could make it stop? It’s very annoying to me, particularly when it’s cold outside and the engine has idled down, but the tranny is still cold so the synchros don’t wanna work that great. So I just double clutch and rev match but with that stupid idle thing it makes it a little tricky sometimes. Gimme your thoughts, suggestions, whatever. Thanks guys.
