Jeep temps drop, then idles around 1000 rpm and is hard to start after
 

Alright so my Jeep is doing some funky stuff any input is greatly appreciated.

When driving or idling temps will drop to 0 and my Jeep feels like it's at a higher rpm that it is supposed to when it is idling, around 1000. When accelerating the jeep has less power and takes more to get up to speed, so rpms go up higher, also my CCV hose is super noisy (idk if that's related or what)

Recent upgrades:
Flowmaster pump/hesco thermostat/195°Tstat/two core aluminum radiator

99+intake/4 hole injectors/port matched/flepro gasket

Rugged ridge(Omnimax) stainless header/2.5" front pipe/ high flow catalytic converter 2.5"/ exhaust dumps before wheel

Computer was reset after upgrades, and was very hard to start after reset (had to punch gas and crank at same time)

Also some times it does not want to start at all, and I have to punch the gas while starting, then it comes up to a normal idle within like 5 seconds.
