hey guys i just installed the agency power lightweight pulley for my ecentric shaft now my car is throwing a check engine light for misfire cylinder 1 any fix for that?

 

I had that happen to me when I put mine on. I also had one pop up when I had my engine replaced.

All I had to do was take off the pulley, clean the mating surfaces really well, and replace it making sure it sat perfectly on the shaft. Make sure that it's not off kilter the slightest little bit because the shaft position sensor is very picky.

I think I also did all of the ecu resets.

Good luck.
