Check for a vacuum leak and check the timing . And check if all cylinders are firing correctly .
Another area to check especially if you already exhausted all the typical intake, fuel, spark issues are you starving the electrical system for power. As you come to a stop the engine has to rely on less electrical since the alternator is now not putting out to full capacity. The battery is in that loop and helps balance power. The installation of a larger sound system can require more power and there-by robbing the engine of needed voltage. (Typically the added system is connected directly to the battery)Example: 1999 Nissan Maxima with a sub woofer added to the sound system will cause the car to stall at idle if the volume range is set too high.Theres been a lots of unnecessary engine parts changed out chasing a stalling problem. The mechanic drives the car trying to simulate the problem, but doesn't think to turn the sound system up to max.

everything appears okay - what could be the cause and how do i fix
The best way to fix the engine light in your Land Cruiser is to fix the problem. There are many reasons your check engine light could be on including a loose gas cap and problems with your engine.
this happen to me about 2 months ago and it was the throttle position sensor [tps].2 weeks after that it did it again and the maf [mass air flow]sensor was bad.both are easy fix's.
often times it either means that the engine is not receiving fuel into the cylinder at the proper timing or that there is not enough fuel coming in to begin with... probably a relatively cheap fix.
You must fix whatever is wrong. Can be minor or major. No way of knowing until you have it looked at by a professional.
you do not fix the light. you fix what ever caused the light to come on. so the lenght of time depends on the cause for the light to go on on the first place.
You do not need to fix the check engine light you need to fix the problem that is causing the check engine light to come on. Most auto parts will scan your ECU for free and tell you the code that has been set. This code will tell you what parts are being effected.
I can say from experience that Restore will stop engine oil leaks. Beyond that I have no idea. NO, they are only a temporary fix.
Check and fix the engine.
