high idle

Hey all, I recently began to run into overheating issues on my 95 FZJ. Everything starts fine and maintains normal temp until about 30 minutes into driving in which the car's idle starts to slowly climb and the temperature starts to go up. I've put a new thermostat in and did a coolant flush...

Hey everyone. If you saw my last posts I was struggling with high idle and multiple codes being thrown. I fixed all my codes and checked my vacuum lines, however I am still idling very high. In neutral I am sitting at about 1500 rpm. Not sure where to start. Was thinking a tune up might do the...

Hey guys, my 97 80 series was idling at around 900 rpm, both in park and shifted into drive. After i fixed the cruise control it mostly now idles at 1,100 rpm in park, still at 900 rpm when shifted into gear. Once or twice it will still idle at 900. Also now when I start up it revs pretty high...

Hello again everyone! I finally bolted on the Aisan carb that I got rebuilt and after a lot of tinkering with it trying to get it to run right, I am not sure what I am missing. I can't get it to idle without misfiring pretty regularly and it has some issues starting sometimes. I have tried...

Hey guys I just bought this 1997 80 series about 5 days ago, ran mint passed a roadworthy and all that but now I’ve come across a few small issues, the worst one is this The Car is On Petrol/Gas runs beautifully on gas and ran great on petrol for the first few days but now all of a sudden when...

Hi, I'm new to the land cruiser world. I've stumbled across this forum and am loving it.... I have a 97 FZJ80 with factory lockers. Truck has 212k miles. I recently got an issue with a fluctuating high idle. (Between 1500-2200ish) I decided to drive the truck as it was hoping something would...

I’ve been having high idle problems so I took of the ISC and cleaned and bench tested it. It extends and retracts per the FSM but when I put it back in the truck it will idle correctly but over the course of a 30+ mile drive the idle will increase and max out at 1300. I have tested the ISC while...

I have an odd and seemingly unresolved problem... no matter what I've tried. First things first... I have an FSM, I have used all of my Google superpowers, replacement parts are all OEM (even the replacement tubes, lines, sensors, etc) and now I'm asking for help. The problem: I have a 96...

Ok so this is an on-going saga that has been happening with BeBe since I rebuilt the top end in 2015/2016. She is a 85 FJ60 with the original 2F in her, desmogged when I first got her due to the smog pump being seized. Issue: - Truck will idle high after it has warmed up. Talking between...

So I have an issue where my truck runs fine when cool and after a few minutes of driving but anything longer than say 10 minutes the engine wants to run at very high idle at all times. Almost 2000 rpm. Anyone had this issue before?

Does anyone know if it is possible to temporarily input a modified signal to the IAC valve to initiate high idle? I'm thinking this might be pretty easy on my OBD1 1fz-fe.

I changed my plugs, wires distributor, rotor and distributor O-ring today. It was hot, but it went well other than jacking with that #6 plug. I had a couple of questions about my experience. I'm an extreme amateur so these may be very basic questions. 1. I split the PCV hose at the end that...
