Hey, been having an issue with my ford, and I don't know how to diagnose it. Half of the time when I start it up, it is relatively fine. But the other half of the time, especially if it has only been of for less than an hour or so, it will bog down super hard when I start it, sometimes killing the engine entirely. and when I put it in 1st and start going, it is still super boggy as if there is very little low end power and is a burden to move forward, until I have an opportunity to just punch it and clear the engine out. Any thoughts will be appreciated! It has been doing this for a long time, im just getting tired of it, and its been a little worse these past 2 weeks.
