Every so often my 1999 Lexus ES 300 does not shift into overdrive and the check engine light goes on and off. It has about 200 miles on it and I do change the oil every 3000 miles on it. Usually put regular gas in it, rather than super because I did put super gas in it for a while and it did not help. Any suggestions as to what it might be?
If check engine light goes off then there is a trouble code stored. You'll need to retrieve the code w/ a scan tool and follow the proper diagnosis.

chances are you don't have to replace the computer. the reason i tell you this is because you did not mention that the car is running lousy. no complaints of rough idle or missfire or hard starting. chances are that your engine speed sensor which sends the signal to the computer which then controls the transmission is most likely the culprit.. and it could just bhe that there is a loose connection between the two. if that is ok then your transmission control module is faulty. this is not the main computer, but the gobetween the trans and the ecm.. hope this helps please rate this...thanks(btw....the knock sensors control timing not the trans mission)

Hi there;
#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps
Farrout!

try to reset this problem , disconnect the negative battery terminal few minutes and reconnect , start the engine
SOURCE: My son's 1999 Lexus ES 300 has a code of P0420 and
a common problem is the vacuum switching valves on the charcoal canister. These are small electrical solenoids with 2 vacuum hoses going to them. When you put power and ground to them they should click. Otherwise make sure there isn't a vacuum hose disconnected by the air cleaner box.
