I live in a hot, humid area. 90 degrees and above

I live in a hot, humid area. 90 degrees and above sometimes 100 degrees. Sometimes when when sitting idle, e.g., at a stoplight for more than a few minutes, and yes, i have my ac on, i feel my car like kind of shake and like its almost going to give out, like my car is going to shut off. i will turn my ac down and i usually never have it on full blast, just on 2. or i will just try to drive up for a foot or two. its like if im constatnly going its fine, but when its hot and i sit for a few mins in traffic it feels like it could cut off. what is this? what do i do? please help!!

    so i should get a vehicle inspection? will my car actually turn off on me one of these days? my last car inspection prob 2 months ago, said everything was a okay. could it be a coolant issue? and it only happens when very hot over 90 degrees and when im stopped for more than 1-2 mintues, e.g., stuck at long traffic light or stuck in traffic.

This could honestly be several different things, but make sure your alternator is charging your battery correctly, have your battery checked as well, and have a ob2 scanner hooked up to it, this can be done at part stores usually for free. Sounds like the engine is having trouble handling the extra strain of an a/c but the only way to single it out is to check it out. good luck

Could be anything from a head overhaul to a temperature sensor , or a duff battery and with everything running and a worn engine the altenator is working overtime to supply enough juice on idle

    the cooling fans use a lot of power and if engine is worn it will not have the power required at idle

My 2003 Lexus es300 has electrical problems but only on hot days above 90 degrees. When driving the electrical power fades on the dash and sometimes clicks out. When you turn the car off it will not start...

Well it sounds like you are loosing the alternator - could be the alternator itself or a connection in the harness. Things like diodes and relays can stop working in high heat conditions.
I would check the output of the alternator the next time the lights start dimming.

Not cooling

your low for 134A should not exeeed 45 Psi and highs for 134A shouldent get above 300. When your replacing stuff are you cleaning out the residue from your evap and condensor prior to reinstalling Freon?allso adding oil. and vacumeing your system prior to charging helps to get all the moisture out. In high humidity its crutial for optimal cooling and when system is open to the humidity for some time it gets loaded with water and vacuming can sometimes take as long as 10 hours

Temperature imbalance is usually the first sign of low freon charge. Have that checked first.
