When I bought the truck a couple weeks ago it ran like a top, started a little hard, but ran great, I took a small road trip with it (1400 miles) and halfway through the trip it would intermittently idle rough, then it started getting worse and now it idles rough and low all the time, I have no tachometer in my truck so I don't know what my RPM is doing. It has a sticky choke occasionally but I'm pretty sure that isn't the problem, any suggestions on what I should do?
