im freaking out man!
 

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?

did u knock a plug wire off

yeah, i don't see how the two are related unless you made an error when installing.

naw didnt even touch them after the cel light came on i called mazda and they said it could be the plugs wires or packs so i replace all of them still got the code.

hmm.

You need to reset the e-shaft profile by doing the "20 brake pedal stomp" reset procedure.

Turn the key to on, but do not start.
Stomp brake pedal about twenty times(quickly) while watching the oil pressure needle until it sweeps all the way to the right and then back. If doesn't sweep, turn off, wait, and then start over.
Turn key off.
Start car as normal, if it's still on, then start over. (Courtesy of "Mazsurfer".)
