I appreciate the input MKS, but the poor gas mileage isn't a contributive factor, it's one of the resultant consequences derived from the principle issue.
This past Saturday, I met up with some fellow Cobra owners at a show in Vistancia. That was a 56 mile drive from the east side of town to the west side, via the 101.
Once I got off the highway and back onto surface streets, the motor acquired some surprisingly fresh, new, and annoyingly worse symptoms. At every light or stop sign the idle would go dangerously close to stalling, then recover after a few seconds. When starting out from a dead stop, the car would buck back-and-forth aggressively as if I was trying to pull out in 4th or 5th gear, and then recover itself whenever it damn well felt like it.
From my research, Imagine Injection in Glendale is overwhelmingly regarded as the best shop in Arizona when it comes to tuning fuel injected Roush motors. (Allegedly) The owner, Bob Ream, worked for Shelby for over 25 years.
I am waiting for an opening where he can slot my car in for a re-tune. I talked to him last week. Based on the engine symptoms I provided, he stated 2-3 hours of his magical touch @ $125/hr should put my 605HP EFI Roush back on it's feet. Stay tuned (pun intended).
