I was driving mi car on the high way and then nitice that i lost speed the check engine light was flashing then went solid and till i got home. turn the car back on and the check engine light was off and still hasn't came back. But i did get the codes P0300, P0301, and P0304 for Random/ Multiple cylinder misfire detected in cylinder 1 and 4. Does this means that the sparks plugs are bad since its giving me the code for those?? Plaese Help and Thanks!
I think this is a Coil problem. try replacing coil. If not, it is a MAF problem. 06 wire should still be fine now.
SOURCE: My C230 Mercedes has check engine light on. Car
P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks.Replace MAf sensor,if cleaning the MAF does not help.
Thanks.
