The Roush guys who flew out here from the factory for this were able to consistently duplicate the issues I described with the engine, whew - intermittent problems are the worst. They ended up having to adust the timing, throttle bodies, fuel/air curves and the IAC (idle adjustment control) on my engine. Evidently they put about 50 miles on the car shaking it out and testing it with a computer on board monitoring the action in real time (hope they had fun
). Charlie says they now have the tuning dialed in and the engine runs great. They also had to replace the spark plugs before any adjustments were made because they found them fouled due the above being out of whack. The car now has close to 500 miles on it so I'm having the routine 500 mile check on it done where the
oil filter is sliced open and the
oil is analyzed. Assuming that doesn't show anything I will pick up the car tomorrow (Friday) morning and ride like the wind.
So again, hats off to Roush for their GREAT customer service -- just extraordinary. This was all done at no charge under warranty. I'm gonna give Todd Andrews at Roush a call and give him a thank you and a big verbal pat on the back. Anthem Motors came through on this too and were invaluable in their help, so a big thanks to John and Charlie at Anthem Motors too.
