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

please help i can not figure whats wrong with my car for the life of me any ideas?

 

wow.. that just happened to me yesterday. My temp was at the same spot as yours and it kept bogging down and the rpm was kinda jumpy. Turn your heater on full blast hot and see if it still does it. I just changed out my thermostat, timing belt and water pump last night after that incident and now seems like it's running okay now, but the temp is still at that same spot as yours. I'll probably change out the radiator to a full aluminium one and see if that helps, cause I'm pretty sure I'm still on my stock rad with 214k miles.

 

yea i tried turning the heat on and it still does that its crazy i need to figure this out because i can only drive my car for mabe 30 minutes then it starts doing this

 

what did you take off to change your radiator? Looks like your main relay isn't working from the video. Check all your grounds if you removed any (from the thermostat housing). If you disconnected any wiring check that as well. Changing the radiator won't cause this its either a fuel or spark issue (both from the main relay).
