    Low idle while in gear at stop...

    Well, maybe continue with the FSM on page FI-70 first. Out of adjustment? EDIT: Just realized I have a '95 4R with a blown HG sitting in my driveway. Time to go scavenging... :clap: 2nd EDIT: Nope, changed the design on the '95. My '89 Pickup has a matching TPS...

    Thank you all- I abandoned and re-routed the vac line. Thinking more and more about removing the EGR and Air Pump system... Double checked the TPS: VTA-E2: .83 PASS IDL-E2 (.03 gap): open FAIL IDL-E2: (.04 gap): open PASS VTA-E2 (WOT): open FAIL...

    Thank you, Jon- a knowledgeable voice of reason, as always. Still learning to use the ohm meter and understanding electrical systems. I've always been a mechanical aptitude type of guy. The electronics aptitude for me has always been a struggle. Had to research the difference between...

    Looks like the AFM is on its way out- E1 - FC resistance bounces around a bit at open position, when it should be ZERO. All other tests come back within FSM spec. (FI-67) Very helpful to have feedback from others to prompt & gain insight. Thank you!

    650 rpm in P & N Just finished checking the vacuum hoses using compressed air. All clear. Snipped some of the ends, but could probably use new hoses, as you pointed out. Intake hoses are new. Does the 3FE have an IAC? I thought it was the AFM, TPS, and ISC for the air induction system...

    Low idle while in gear at stop...

    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...
