I have a s13 original 5 speed ka24de. It starts up fine and idles then drops and stalls out. It will stay running if you give it gas. the gas responds very well, revs up easy, but then drops back down and cuts off with out more gas. as it warms up seems to get somewhat better but not grate. I tightened the throttle cable, (more that it needs to be) and now it idles very high then tries to stall and back up to high. motor doesn't seem to want to warm up ether. Im sure the temp is reading wrong. right? car had a blown head gasket but has been fixed. any Ideas?
