Hey guys, I'm having a problem with my check engine light continuously coming on. Last night I did an OBDII scan, and the result was a P0170 code for fuel trim malfunction. What does this mean? what is fuel trim? and how can I fix this problem? The car is a 94 C220. So if anyone can help me out, i would be very thankful.



take care
