Saw this on here afrom a while ago and it's the exact thing going with mine. So how do I fix it?----Replied on May 19, 2010
I asked about what would could cause hard and no start/ rough idle and no rpm. I appreciate your suggestions. The problem was a plugged exhaust system. The ls primary cat had broken up and plugged the system. I disconnected the exhaust and the thing fired right up.
