hey everyone im having a problem with my cls engine. I had a code that was reading a miss. so me not thinking right sent it to my mechanic and told him to replace the engine....so a long story short it still has the same problem...its driving me up a wall...my next thought was that the catalytic converter is bad. and also the check engine light is blinking never saw this before..can someone please help? thanks

 

Before you replaced the engine, did you ever find out what the error code was?
