Hey everyone. I have a problem. I have an 87 Firebird wth the 305 and 4BBL Rochester. I just got the car and changed the cap and rotor the other day. Since then I have noticed that my idle fluctuates, and the motors is missing while driving. I had a hard time taking the rotor off and had to use a lot of force to get it off. I was wondering if maybe that while trying to get the rotor off the distributors position changed and messed up my timing. The timing was off before and seems to be a little worse now. I haven't had a chance to adjust it yet. Just wondering if anyone had any other ideas of what else to check after I reset the timing. Thanks.
