rough idle no codes

[ateamplumbing]

I just bought a 1994 J30 with 41,000 original miles. The car is immaculate! I am having an issue with a somewhat rough idle. When the engine idles, it will idle rough sometimes but not all the time. Car has no issue at acceleration or high end rpm's and has lots of power. Any ideas on what the issue may be? I don't want to just start replacing things without some insight! I added a can of Seafoam to the gas to see if that helps.

download the FSM (service manual)
you got a great car, but expensive to maintain....if you can do work yourself, you will be ahead of the game....
