Recently we had the timing belt and water pump replaced on our 02 Cruiser. Shortly afterwards whenever it was put in park or idling it would begin to shake and shimmy. My wife took it back to the mechanic mad as you know what!!! He hooked it up to the scanner and a code for the EGR came up. We spent way more than I wanted to for the timing belt/water pump replacement. I checked the Haynes manual to see if I could replace it myself if possible. Forget this! Would a bad EGR cause this shaking or maybe the PCV valve? How about the plugs? Thanks
