Very high idle
10

Asked by Flareside92 Feb 05, 2019 at 12:31 PM about the 1992 Ford F-150

Question type: Maintenance & Repair

So i have a 92 Ford F150 Flareside that I am
rebuilding. 2 WD, single cab, 4.9L straight 6. I just
replaced the whole exhaust system. Everything
from the manifold down to the pipes are new. It
always had a high idle, around 2500, but i figuted
this would have remedied that. Unfortunately, it
hasn't. It still has a high idle, and i cant figure out
why. Anyone have any clues?

I've checked the tree and followed all the lined to look for any breaks, everything looked good. The booster looks like it may have a leak, would this be the leak i am lookong for? Or could the throttle position senser be the culprit?
