Many thanks a.graham52 for the factory data...looks like I may be on the right track for a change.
03glgold - Regarding the 1200 RPM: yes, it seems to steady out with more RPM; but I'm not sure if that's just more crank rotational inertia helping it along, or the FI's being open longer due to higher demand (lower initial current draw maybe?)
Just to add for historical data: ohm'ed out the FI's, all look OK.
Any idea where the FI ground is located? This car seems to have an above average amount of corrosion.
I will report back any further findings; I will recheck the misfire code and start ringing out the FI harness wiring.
