    IAC Replacement

    Thank you for reply. Sometimes, hot or cold I have high or low idle. It always slowly adjusts back to 600-650 rpm. The LC has been in my family since new; if the throttle body was ever off, it was a long time ago. I will see what new iac wiil do when it arrives; hopefull they will include a...

    IAC Replacement

    Thanks ZRTacticall and Malleus. When the engine is turned off, does the valve always go to full open or does it open gradually as ect goes down?

    IAC Replacement

    I have ordered a new IAC for my 97 LC with 290k miles. The existing IAC failed the test listed in the FSM; idle speed is sometimes poorly controlled. Will the computer have to learn the new IAC?

    FZJ80 Running Woes

    Thanks so much for your detailed reply; I have ordered a FSM which should be here in few days so won't need your generous offer to send me a copy of the procedure to measure fuel pressure. I am having an intermittent hot start problem so fuel pressure drop after engine shut off seems a good...

    FZJ80 Running Woes

    I have nothing to suggest regarding your problem as you are way beyond my ability. I am a new owner of a 97 LC that I think I may have a fuel pressure issue; assumings yours is the same, where to you hook up a fuel pressure gauge and what sort of adapter is needed. Thanks and good luck with...

    Paint rear fender flare

    Regarding the rear fender flare that attaches to the rear door, there are two screws visible with the door open. Are these two screws all that hold it on? The paint shop wants to take it off before painting. Thanks

    Intermittant High Idle

    97 LC with 290k. When cold it always starts perfectly; fast idle at 1200-1300 then idles down to 600 over a few minutes. When hot also starts perfectly at 800-1000, then immediately down to 600. Normal idle is so smooth when stopped that barely anything can be felt through the steering wheel...

    WIX oil filter

    I'm new but have used wix oil filters on many vehicles; is there an issue with wix for the 97 LC? I remember seeing something to that effect. Thanks

    Thanks, I will replace the oil cap; it has no seal. Does the iac give trouble or require cleaning?

    New to me 80 series

    The car was stored over the winter, but I've been driving it daily for over a month. I'll take the air intake hose off and inspect and start replacing vacuum hoses as they look old. What is the issue with the oil cap? Thanks

    New to me 80 series

    There has been no recent service and the oil cap is installed. The engine died like the key had been turned off and started right up after I got the car stopped. The air conditioner is a possibility; I believe it was on. Does the compressor cycle when the a/c is on? Thanks for your reply.

    New to me 80 series

    I recently got my late brother's 97 Land Cruiser with 288k miles which he bought new. I've driven it on a couple 100+ mile trips and around town; it drives great and engine idles smoothly and is very responsive. I had one disconcerting experience; while coasting up to an intersection at 15-20...
