2.9 fueling issues

Hello,

New to this site so save your time by calling me a newbie if I have put this post in the wrong page.

I bought a 1987 Ranger with a 2.9 V-6 about 3 months ago. When I bought it, it had been sitting for about 8 months so it was running pretty darn rough.

So far I've changed: (engine wise)

Plugs, plug wires and cap

Fuel pressure regulator

oil, filter

cleaned out the Idle air controller

ran a bottle of sea foam through it

new air filter... And I believe that is it... I've been driving the truck for about 2.5 months and it has some sort of fueling (my best guess) issue. However its not ALL the time. While driving it, it will have a sputter and will make the truck fells like it almost has a miss. I have noticed that it doesn't do it as much on warmer days. The idle spikes high when I start it then calms down to around 1200. The truck has about 120,000 on it. I was told it could be the gaskets for the throttle body intake but wanted to get some advice before I delve into that project.
My theories have been a leak in a vacuum line somewhere, or a bad fuel tank or dying fuel pump.

Any help at all would be appreciated. If your planning on leaving a comment like "maybe you should buy a new motor newbie" than save your time. Helpful tips only please, I'm a busy guy.

Last week I drove the truck on a 50 mile trip with not a single problem then this weekend and today it's sputtering like crazy. Also...I filled the tank up for the first time yesterday and fuel was leaking out for the tank and pump (housing?).

Anyways guys, any help would be great. I'm really fit to be tied with this truck but will need it for work.

Thanks
