You have to remove the dist from the motor. Take the cam gear off and remove the dist. shaft from housing,use plenty of p.b.blaster/wd40 to make it eaiser . Then remove the module and little clip holding the coil in place. You can do it but if your shaft wont come out you might have to get another dist. When the shafts get tight on tbi engines it will cause high idleing and loss of power under load. Hope this helps,Erick
