I just purchased a 94 Wrangler YJ w/ 4.0 5 speed it idles great, but as soon as I drive it it wants to bog out and sputter like its running out of gas. If I let off the gas it will smooth out for a second as soon as I get back on the throttle it goes right back to sputtering. Here's what I've tried: fuel filter, dist cap, plugs, plug wires, drained gas tank, removed injectors cleaned in a pan of gas w/ a toothbrush re installed. It ran great for a few miles then back to sputter mode. Any ideas on what to try would be greatly appreciated!
