OK so i put in a civic radiator in my 1991 DA integra so then it started to over heat and do what its doing in the video...so then i took out that radiator in put my stock one back in it does not over heat but still does what the video shows you
its starts fine and runs good until it starts to heat up for a while then it will start doing this

in most of the video when the rpms drop to 0 im still holding gas pedal
and when it turns of it takes a while to start the car
and its just not the gauge messing up
has stock ls
