ok so I have done my research. My car is odd. its a 92 ka24de. When its cold like the first drive of the day it runs perfect. But as it starts to warm up it starts to cut out at hight rpms. Pretty much it feels like its fallin on its face at 3900 rpms. And mean while the battery light is on and flashing when you go higher in rpms. ( kinda like a blinker) I have had the alternator tested and the starter tested. I have gone through and scrubbed and cleaned all the grounds.. Whats next?!
