No, the only problem that has happened twice recently is that as I have slowed to pull into a parking space, braking and turning the steering wheel, because of the low revs the engine has almost died, hence losing power steering/brakes.
Any ideas other than a reset?.......Mind you I've not reset it since I added the extra air flow with the ram air jobby, could this be something?
Steve, the revs go up slightly with the A/C on.

Blimey, thought it wouldn't be easy:confused1:.......lol.

A reset is definitely worthwhile, can't hurt and it might just help.

IS200 Turbo project now just about complete ! See my thread here and leave your comments.
Now running standalone Syvecs ECU and no stock ECU !

steviewevie The accelerator pedal operates a cable which is connected to the throttle body. A sensor there measures the opening on the cable, which feed a signal to the ECU. The ECU then tells the throttle body control motor how much to open the throttle.
In the event of a malfunction the electrical control drops out, and the mechanical throttle cable directly operates the throttle itself.
Similar to the Mk2 Aristo then. No adjustment screw? how's the cable adjusted? don't happen to have a photo?

Your air filter shouldn't effect it in reality, but then...........
If you're stationary and turn the steering, do the revs pick up?
Does it only do it when warm?
Although I LOL at the internet phenomenon of 'resetting the ECU' for any fault, it may be worth it, but could be many things, vac leak, idle control motor etc etc

Just having a search for some info on the throttle body as i cant remember whats on that side now i havnt got my lex?
Might just have to buy another is200 so i can play with it again :laugh:
Lexus IS200 Sport Navigator (Now being stripped again) :blink:
Now Don't Forget The REP!!!
Keith can you adjust the cable on the throttle body, so it pulls it up a touch for the meantime?

08-07-2017, 04:43 PM #17Pretty sure there isn't an idle control motor, just a throttle body motor. I similarly don't think the ECU reset will magically fix it, but it doesn't hurt to try

Info on checking it here.
Diagnostic chart here (check the section on "Low engine idle speed", where it suggests a/c issues, neutral start switch circuit, injector circuit, or backup power source circuit).

Cous3 Steve I noticed on the "Info Checking" that it says "650 +-50" so maybe it's not too low?
Yeah, I'd already seen that. But you said you think it almost stalled ? Which wouldn't be right. As you say an idle speed of 600 should be ok according to the manual.
