1990 yj

I just received a 1990 Wrangler YJ from my inlaws. It had been sitting for 10 years. I have it running but have some issues when it is cold. It runs really bad like on only 2 cylinders when its is cold but when it warms up it runs great. It has a 2.5 throttle body. I have changed cap and rotor. Any help would be great.

Try draining the tank then fresh fuel and gas additive.

Thanks for the help. I had to change plugs again. There were two that were cracked and had a lot of carbon. Runs great even started fine in 26 degrees. Now I have to fix the steering.
