When it is in park, it's fine runs good. When put it in any gear the engine sputters. Messed with electrical plug on side of transmission drove fine till I hit a bump. I tried to do the same thing with no luck. Before all this started, it ran great until I hit a bump then the trouble started. Pictured is what I messed with.

This is common when the spark plugs, plug wires and coils need to be replaced. Here is a video to show you how to fix the problem which is done on a similar engine, but the procedure is the same and I have provided the instructions for your engine in the images below.
