hey guys i did a search but could not find an answer to this...its very wierd...

ok,

when im driving say doin 50-55 and come to a light thats about to turn red or even when i come to a stop sign and i apply the brakes for some reason my car just dies... it shuts off... what can it be??

btw its a A/T 1992 lexus es300

 

so you step on the brakes and it dies?. i'm not an expert but it seems like your battery is dead? in addition, your alternator too... have you change either or know that its in good condition?

 

batt and alt are good as i can tell it doesnt always die but yes when i hit the brakes it shuts off for some reason only sometims not always

thanks for your reply i will check those

i hope someone else has more input on this

 

Check

-Grounds
-Vacuum leaks
-TCC solenoid

Most likely the grounds, just upgrade to a lower gauge

 

After filling my tank at the gas station, I started my car and then it died. I started it again and it died again. So I started it again and then revved the engine because now I was getting mad. After a few seconds of revving the engine, I took my foot off of the gas and it died again. Anyone know what the hell is going on.
I can start it and then rev it up and hold the brake at the same time and then put it into gear and release the brake and I can go but as soon as I slow down enough to where the RPM's get below 1000 it dies and obviously all of the electronic **** shuts down too. ie powersteering, brakes...etc..
I spoke to a service guy who said it may be my O2 sensor or it may be my fuel computer module? PLEASE HELP ME! I WOULD APPRECIATE ANY AND ALL ADVICE. ONCE AGAIN THANKS

 

have you ever try messing with the throttle? the car "should" idle @ 700rpm and should be fine. anything less the car would likely stutter and shuts off. adjust the throttle alittle bit and tell us how it goes.

 

-Any check engine light?
-First thing i would check is the idle air solenoid

 

im a new to this lol i dont get it

 

I had the same problem on my ES300,and I'm pretty sure it's your ISC valve
(Idle speed control valve) it's located just below the throttle body assembly,
it probably just needs cleaning or worst case is that you may need a new one!
(I'm a Toyota/Lexus technician)

 

wow. i'm glad someone else here instead of Phenoix giving out all the good advice.. i hope you stay put and help fellow CL memebers out...

 

Sounds like you have a hybrid

I had this problem too, and the ICS's in these cars are a pretty common issue, so add a vote for that

 

!!! wow!!!

thanks alot man im deffinatly goin to look into this!

is this something i can do? is there a How to on how to safely do this?

thanks alot for your help

 

This sounds like the same problem I am having! Im gonna take it out this weekend. How would you go about cleaning it? I mean what kind of cleaners?

There is a thread in the LOC site with pics of the throttle body cleaning process in a '95 ES. See link below.
