I did an install where I had to disconnect the battery. After I was done and reconnected everything, everything appeared to be fine. But this morning I noticed the "Check Engine Soon" light come on and remain on through my entire commute. Has anyone else encountered this issue? How do I fix this? Thanks

 

you need to read teh code to determine whats wrong. usually leaving the batery unplugged will clear the codes.

 

sorry dumb question. read what code? can I clear this light by unplugging the battery again?

 

Take your car to a parts store or the dealer and have them read the code. Your check engine light comes on when something triggers it, the code will tell you what it was. It's part of the OBDII system.
