1999 Lexus ES300 ProblemsCheck Engine Light Due to Failed Oxygen Sensor
The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.
On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.
Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.

AC BLOWS HOT AIR. ONLY THE PASSENGER SIDE COOLING FAN IS RUNNING.
I put a new alternator on a new duralast gold battery new serpentine belt
The AC has always been ice cold. However, all of a sudden it blows warm air. It went from fine to not fine. Does it need a recharge or does the rudeness mean it's the compressor. Any way to check.
