Check engine light on in 93 Lexus

For which component or system?

Hello. I want to know more first, does it only make noise in motion or all the time?

This is my drive cycle a generic drive cycle i have used many times over the years and it has never failed me most drive cycles are too specific and impossible to adhere to for most drivers follow these steps exactly 1. make sure all codes are cleared and no check engine light is on 2 make sure the fuel level is between 1/4 and 3/4 full (this is part of the enable criteria for the evap monitor to run ) 3 let vehicle set overnight 4 start engine and let idle until the temp gauge is in the middle (this cold start enables the evap monitor and runs the O2 sensor heater test )5 drive vehicle around town avoid the highway stay at below 50 mph and when stoping at lights remove your foot from the gas and coast from around 50 to about 10mph or less if possible this will run the EGR monitor after about 3 to five miles of this proceed to the highway or freeway and travel over 50 but under 70 mph for about 3 to 5 miles this will run the catalyst test provided the O2 monitors passed if they didnt you will have a check engine light on before this point also i do a coast down on exit ramps (no braking) they make great places to get that EGR to run ONCE YOU START THIS PROCEDURE DO NOT KILL THE ENGINE OR SOME OF THE TEST WILL FAIL TO RUN

My Lexus es 300 most often when engine is warm will not shift in to last gear. Stop engine start it will shift ok when engine is cool. engine pings kock senores. When in gear at high speed the car runs like new?? Car run bad in hot weather. VSC light on. Red light looks a circle with red line through it comes on not always..

Hi, did you ever get an answer? I have the same issue. Thanks.

ENGINE COULD BE GETTING TOO HOT.CHECK ANTIFREEZE LEVEL AND TRANSMISSION FLUID LEVEL.

I had check engine light and TRAC OFF. OBD-II MIL code was P1133 which is Air Fuel Ratio Sensor Response Malfunction and scanned by AutoZone. After disconnecting the battery for 10-15 minutes, the lights went off. I cleaned the gas cap and tightened it firmly. For the last 400 miles, the lights have not come back. When scanning using Snap-on one, no code was detected. I think gas cap was the reason for the lights.

replace spark plugs, spark plug wires, cap, ignition rotor, air filter, oil change, transmission flush, transmission filter&gasket .. That should do it.. It'lI be good if you could check your timing as well.. do this tune up every 15-20 thousand miles and oil changed every 3000 miles, depend on how much you drive it.

is the check engine light on while driving?Also when u crank it do see the check engine light come on and then go off?
