So about a month ago I did a clutch change. Along with the change I installed a UEL Header and a Borla Catback. Since then my car has not run correctly. I didn't drive it much since i wanted to identify the problem. While it was running the rpms would fluctuate and the car would eventually stall. Me and my dad have been diagnosing it and after several possible causes, we remembered the flex plate behind the flywheel and considered that it might not have been lined up correctly. So we decided to go ahead and pull the clutch back out and see if that was the problem.
Here is link to the picture from the flex plate and im trying to figure out whats going on here. So there is a hole which i thought was for the pin to line up but there is also a indent in the plate. It lines up either way whether you line it up on the hole or the indent. Because when we pulled it out the second time we had it lined up on the hole. I was just hoping someone could confirm whether the indent is possibly from another owner installing the flex plate incorrectly or if its supposed to be where you line it up. Thank You!!
