My car won't start. Its been looping and sputtering when its too cold or too hot on 1993 Nissan Altima

Its got about 350,000 miles on it and I have had it for a few months. I do drive alot. I drive to murfreesboro and back two days a week and nashville and back four days a week. I very easily put 368 miles a week. The car had a tune up when i bought it. ITs been looping and sputtering when its cold or too hot outside. but if I start it up let it set for a few minutes until the RPMs reach 1 it will run just fine. There is no trouble codes showing and the check engine light isn't on. It only runs bad for a little bit but if I turn it off and start it again it starts to run just fine, not looping or sputtering.
