ok im new here and i have been searching for ever......i have a 1993 sc300 and its driving me insane right now....when i bought it i checked the ecm codes myself and it gave me the one for the main 02senors...i changed them and it was running better but not its worse than when i bought it... now the engine light wont be on while driving then out of no where come on and the car acts like it want to die then when i try to check the code either the light stays on or it blinks non stop without any pauses... just this morning the engine light is on and stays on and my car accelerates like and old lady on a sunday... please help

 

misfiring??? when was the last time that car had any maintenance??? spark plugs, wires, oil change, timing belt, etc...if its been a while or u just dont know id make those things happen..preventative maintenance is the key to a happy sc...

 

thanks for the reply "scviolence" but i havent really checked and i do not know when the last time it had maintenance but i agree with you......thats the best way to start trouble shooting.....but i went to check about an hr ago the error codes myself and now it just blinks with out any pause

 

Respect the Car and it will Respect you.
Give it a Full maintenance like the other guy said, Nothing is better than being able to "See" Your engine bay. and Knowing What you replaced Fresh, So you know where to trouble shoot from. Best of Luck man!!!
