Cylinders dropping out on highway
Hi guys! I just bought this 92 yj. Guy before me had it 19 years well maintained. He told me when I bought it that it needed a computer. That he had replaced a bunch of parts and gave up. I bought the computer truck ran much better as it was having problems starting and I had previously had to do the key trick when it acted up. So now at one problem seems fixed I have come across another. When driving typically on the highway but not always its as if all cylinders drop out. Either from fuel or spark. These parts were replaced right before I bought it. Cap, rotor, plugs, wires, coil, crankshaft sensor. I have replaced the computer and the tips. Problem still persists! Again truck will completely cut out for a split second then continue on driving. I'm in need of answers. Thanks!
