For some reason my car engine shut off when I stop and only in the morning when the weather is around below 65 degree. Here is the modification I did to the car: motordyne 5/16 copper iso thermal plenum spacer and aem intake and earth grounding.

I live in az, on summer time is fine or in the afternoon and its only did it in the morning cold weather.

I checked the engine bay and touch it is freaking ice cold. Is that because of the spacer keep it cold and engine shut off since is not warming up???

Please help. Thanks

bump bump and super duper bump for no one here to know the problem
