    Re: 1995 Toyota Previa sc/awd low idle issues

    The IAC valve is what the ECM uses to control the engine's idle at any given time. The ISC valve would be activated with the AC switch to raise idle when the AC is activated.
    The higher rpm cold...

    Re: Broken exhaust flex pipe, exhaust removal

    Thought I might tack onto this since I just replaced my whole exhaust last year.

    My van had a horrid exhaust on it, the flex pipe was severed off at the front from rust and age; the cat was...

    Re: '97 Previa RWD VERY HIGH IDLE Warm Engine

    Personally, I would start with the T-Junction. It's easier to get at and 9.8 times out of 10 will solve the problem.

    On my left hand drive van, it had the high idle issue; cleaned the T-junction...

    Re: A few questions

    New update:

    The Van has been doing well. As weather warms up, I've been driving my project cars a bit more.

    Today I fixed the EGR for good. As I suspected, the passageway was still clogged....

    Re: A few questions

    I finally got around to checking the EGR valve and now have an update.

    I scanned in the pages from the FSM for this DTC, so I am now armed with what Toyota considers to be the causes. However, I...

    Re: A few questions

    Yea I'd have to look in the FSM for 95 to see what the EGR codes are, and their criteria. My van is quite weird, it has an OBD1 port under the seat but also an OBD2 port under the fuse panel cover. I...

    Re: A few questions

    I pulled vacuum on the small nipple on the EGR itself, and pulled vacuum on the bottom of the modulator. Just like I did with my Corolla to determine it needed a new modulator. Both were a-ok last I...

    Re: A few questions

    That was the very first thing I checked. I pulled vacuum on the EGR and the modulator to ensure they are functional.
    The EGR system on late 80s and most 90s Toyotas all work basically the same from...

    Re: A few questions

    Transmission - Yes I think I'll probably just do a drain and fill, replace the filters and the pan gasket.

    SADS is fairly low on my priority list right now considering it seems to be ok despite...

    Re: EGR Cleaning Question

    I see that you have an SC van, so I would take a guess that your high idle is actually likely to be the black flakes in the coolant T-junction by the IAC and air intake hose underneath the front...
