possible bad contacts in wire connector

A constantly blinking check engine light means you have a misfiring engine that is bad enough to cause your catalytic converter to go bad! Take it to the shop... probably means ignition parts and the upper manifold has to come off... and that's no fun! Good luck.

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..

my 1997 lexus es 300 engine light and trac light on.

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.

A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.

try to reset this problem , disconnect the negative battery terminal few minutes and reconnect , start the engine

if not a loose gas cap then what might be the problem

i have a es300 95 check engine light on sometimes it blinks car putts in park,in drive,when ac on the putts worst

Quite often that is to do with your Gear Position Neutral Safety switch.
