Question 82 XLT Lariat stalls while idling in drive

Hey hey, I am super new to Broncos and just bought an 82 XLT 5.0 Lariat. It has a "rebuilt" Edelbrock Carb as well as Edelbrock 650cfm intake. I am having a few issues that did not happen when I test drove it.

It has stalled while idling in Drive. At red lights as well as when I lay off the gas to turn. It doesn't happen all the time. It does NOT stall in Neutral.

Also, the truck also began to jerk back and fourth at around 50-55 mph. This did not happen in the morning but did this afternoon.

Any ideas?

Thanks

The jerking back and forth sounds like ignition problems.

Inspect the spark plug wires. They are probably due for replacement.

idle death = vacc leak. or carb out of tune.

Thanks for the advice, I will check the wires tomorrow.

As far as the vac, looks like its leaking for sure. I was rummaging through the boxes of unopened parts that the guy had in the truck when I bought it and there was some valve seals in packages. Maybe I will jump into this tomorrow, I will have to search the forum for a good tutorial inspecting/replacing. I appreciate the pointers!

eddelbrock.com has a great video collection on tuning the carb. believe me, i knew nada about carbs before using it, and now mine runs pretty well.

but, nothing will matter until the vacc is fixed.

UPDATE:
It seems to be way worse when the AC or Heat Defrost is on. Just testing the vacuum from the bottom right nipple on the carb and it was steady idle in park at 18. Going to do it in drive now with the heat/ac on and off. Could it be the idle throttle on the carb? I really need to put a tach on this thing.

the carb does not have a idle control valve it only has a choke and fast idle. I would double check for vac leaks then adjust the choke and idle per the carb manufacturer.

Oh ok, I kind of figured but I have read so much about the IAC on this forum I had to wonder. I'll double check the vacuum again, I cant decide whether I am going to try and tune it myself or take it in on Saturday. Then again, how are you going to learn if you don't do it right?

UPDATE: So the truck had a lifter tick and I had to lifters to replace them so I opened her up yesterday. Would you believe that the carb bolts and intake manifold bolts were all just about finger tight... After replacing the lifters and intake gasket (also the valve cover gasket) we put it all back together and the truck started right up. I let it warm up and then cranked the Heat full blast and took it down the gas station. Did not stall at drive idle at any stop lights or when turning. Here's to hoping my issue stays gone!

How did the bottom of the lifters look?

They didn't look all that warn but I had the parts. There was one rocker arm that was loose and causing the tick. When I bought it last week the guy gave me a bunch of things he had just ordered. The bottoms were still seemingly flush though.

If there's any wear on the bottom, then the cam may be shot too.

Can you post pics?
