Started the SHO this morning and it was running a little rough, it was running fine when I got home from work yesterday. I didn't think to much of it and thought it would probably settle down. I got about a mile from my house and it will barely run now. It will idle rough, if you try to rev the motor at all it will sputter and pop. The tach is also working. Just to see what would happen I unplugged the CID and it would not start at all, no tach either. I'm thinking the CPS and am going to swap it out. Can anyone think of what else it could be? Thanks.
