Trying to chase this down, with no luck so far. Last weekend at the end of a high country tour day, the Cruiser died on me a couple of times. Crawling, brake on.
Idle is good in P or N, but when put into gear, it drops down around 450-500 RPM.
Just recently replaced plugs, wires, cap, rotor (OEM) a few months back. FPR, FPD, and fuel pump replaced 2 years back or so. Checked vacuum hoses; found one from EGR that the steel tube was rusted and rubber hose plugged full of rust crap. Cleaned steel tube, replaced rubber hose, no change. Checked all aother vac line connections for decay/debris, all good. Removed/plugged vac hoses to EGR system, no change. Recent valve adjustment (thanks, @SUMMIT CRUISERS): is running great on the highway, but still has the idle issue at a stop while in gear. Removed/plugged vac line to brake booster, no change.
Beginning to suspect fuel injector(s) or ISC? ISC check is OK for continuity (installed), same readings as 2 years ago. EDIT: TPS? Also checks OK for continuity. I have not found any better info after hours of searching- I have a trip planned for next week and would love to have this put to bed, as it is our only working rig at the moment. Please help, and Thanks!
