Car gets up to 103c while sitting idling in 50f weather. That's 217f, seems high, right? Replaced the entire coolant system around 10k miles ago so would doubt it's that.

No code for cooling issues but I do get both codes every now and then for DISA and exhaust manifold pressure sensor. It's a black cover engine so not the normal CCV system instead it's built in to the valve cover. Had an issue with that months ago and replaced just the valve.
Seems to be running slightly rough or bounces at low idle. So ordering parts for those issues. Also the vac lines look good. Slight leak on the valve cover under racing conditions.

Battery is only a few months old and gets trickled charged. Battery check good and good charging on Carly.

Ideas and if the coolant temp is an issue? Thanks!
