Okay, I have a 2015 GT, 6 speed. Put long tube headers and a 2018 intake manifold on it.
sometimes when I start the car I get a really hard, vibration, and it starts but it's like I don't know seems like it might be binding or teeth are not meshing up perfectly. It's not a grinding sound like a typical starter issue. It lasts for 1-2 seconds and goes away.
Here are my thoughts.
1. Motor mount came loose and for some reason during start up it's shaking really bad at first.
2. Second thought I might have a kinked vacuum line that opens up when air starts going through it properly.
3. Starter is going bad. I have experienced a starter going out before but this does not seem like it.
I have drove the car extremely hard since install with no issues what so ever at speed 145 MPH plus. Motor doesn't have any idle issues. Sometimes you will see a little fluctuation in the rpms. Not really what I would consider abnormal but a little more noticeable. oem Vacuum gauge on dash sits at about 20-21 hg. at idol. Sometimes when driving I notice the shift not has a little more vibration to it. I figured that just come from the vibration from the long tubes. Any ideas would be helpful. It's a small issue. I don't believe its a motor issue.
