So after driving my SC in the city, when I come to a complete stop I noticed theres a red battery and oil thing that comes on in the bottom right of the dash and I realize I died out. So I start the car again and my idle is VERY EXTREMELY LOW at like 1,000RPM and it's on the verge of just dying out at a stop. I put it in Neutral and rev it a little bit and it keeps dying out, until finally we move and it's better..... Now does anyone know why it's doing this? I have a very crappy intake "Injen" maybe I should go back to stock intake?? I cleaned the throttle body like 2-3 months ago. Do I have to adjust the hex screw near the TB?? I have died out about 3 times on 1 trip. One of the time being when I just drive and push the brakes, I see the light just come on, notifying me that the car is off. Any ideas?! I can't drive this car if it's gonna keep on dying out.

I would suggest trying the search feature, but if the car was running fine before U put on the new intake, problem solved. Go over the engine compartment with a fine tooth comb, check battery cables, ground, gasoline, etc. Post when U fine the problem and good luck probably something very simple.

Sounds like an alternator problem to me.

Did you mean 100RPM????? Because 1KRPM is a tad high at Idle, i would expect that on a cold day.

Yes it is 100 RPM my bad.. and I don't know how the car ran before the intake because when I bought it, it already had that Injen intake on there. Should I buy a stock intake? My girlfriend said the Injen intake is way too small and not enough air is being sucked in which is why the idle is rough and dies out I don't know.

I'm no expert, but I've heard the MAF (mass airflow sensor) can be temporemental when intakes are added....that would be my random guess. Will the car run just fine if you remove the intake? or just remove and put stock airbox back in there?

check the alternator and battery first.

It can also be the MAF sensor if it has one.

Common stalling issue is the fuel pump ecu. It is located on the back seat panel, driver's side, right underneath the window. There are probably 4 ways to solve the stalling issue in first generation lexus V8s, thats the one I faced.
