1999 Lexus RX 300 • AWD Manual • 148,000 miles

While driving my car, the engine will all of a sudden slow down even when I have my foot on the gas. RPM's will remain constant. The check engine light is on and sometimes starts flashing.

Check engine light on

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.
