As long as the motor is easy to work on, I replace the water pump. Inspect the OptiSpark. Install new vacuum line from the OptiSpark to intake. There is an oil seal behind the Opti so I’d replace that too. I had this seal go out and it trashed the OptiSpark. Also be sure the throttle bore is clean and the IAC is clean and working. Skip White Performance provides many high performance racing and engine products such as, stroker engines, turn-key engines, cylinder heads and pistons
