Update: The exhaust leak was repaired yesterday and did not improve the performance of the Sport. Replaced the coil packs, plugs wires, and plugs, no change. One of the questions is if there is a bad connection on the coolent temp sensor of a failed sensor what would the effect be on the performance of the engine. My nephew describes the engine sound, now that the exhaust leak is fixed, as if there is bad valve rattle.

The 1995 DOHC is probably OBD1 so I don't know if it has a knock sensor.

Any insights from any of you will be appreciated. <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" />
