Do you have a wide band?
Check for vacuum leaks?
Check the timing?
Check ecu for codes?
Check your spark plugs?
Check for a boost leak? All of your couplers are tight?
TPS is good?
FPR is good?

I think that's coolant temp sensor, the overheat warning. If you suspect vacuum leak pinch the pvc vacuum line. If idle settles, make a boost leak tester. I'm also assuming your timing is correct, but you have to have a good working base to even know when somethings wrong. Post a video of the idle.

was one of the coils packs... was still sparking too... just lagging not fully sparking so injector was lagging too I THINKK AND HOPE

THERES NO BOOST LEAKS HAVE 4 CUPLORS ON THE WHOLE FMIC ALL CUSTOM ONE PIECE

AND CHECKEDALL HOSES EVERYWHERE MUTI TIMES

waiting for new ones let u know if shes running great after that
