Custmore driving and car stalled. Towed to shop put plugs in the car and started but runs terribly rough. Put a ignition module on ruan the same. Kinda sounds like exhuast is plugged. Any ideas

That is possible, but I would check the egr valve could be stuck or clogged, (clean it first before putting new), then I would check the mapp sensor could be clogged or just no good(beyond cleaning)
