My 96 lexus es 300 has blinking check engine light that comes on the car acts like it is goign to stall in idle and when it is driving. The check engine light will then stay on. Periodically blinking and sputtering and then it will go off and drive fine. The mechanic says the diagnostic is cylinder 4 misfire. He replaced the spark plugs and coil, it is still doing the same thing. Also when it goes into the blinking mode the car smells.
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
