I was hoping someone might narrow it down with the following symptoms/clues:
1) idle (low, and now surging and falling until the car stalls)
2) now occasionally crapping out at high RPM (right around Variocam actuation - ~4500 RPM)
3) a little bit of surging under load at any RPM at all times. (barely noticeable)
4) Put in 5 gallons of gas and the car is magically "fixed", Coincidence?
5) and its getting worse as time progresses
Anyone have insight or a good guess at what problem or failing component would account for all of the above?.
