I have a 1993 buick lesabre that overheated on the hwy doing 70mph after cooling off realized the radiator hose came off the bottom of the radiator. Put that back on and filled coolant levels. It was hard to crank at first. I replaced the oxygen sensor and now cranks easy. But won't idle unless up tap the accelerator, after that it idles fine. There is no smoke coming from the exhaust pipe and no check engine light. Any help would be appreciated.
