1995 Kia Sephia engine cold starts, smokes, and poor accele

Hi obe2811 and TY for the donation

Do you have a check engine light and when was the last tune-up please answer this question

What's the color of the smoke? Blue, Black or White

Hard start could be caused by a coolant temperature sensor not telling the computer to enrich the fuel during cold starts, a fuel pump relay that's acting up and intermittent problem with the ignition switch and low fuel pressure due to a weak fuel pump-Recommend a fuel pressure check.

NO acceleration could be a throttle position, Manifold absolute pressure sensor, MAF sensor, retarded ignition timing could be a transmission slipping
