Well the check engine light probably is blown out. I'll have to figure out how to get at it next. I did however check the EACV, the resistance was only about 1.5 ohms, not shorted to ground, so I changed it with another unit with a resistance of 13 ohms, now the ECU light flashes code 9 after resetting the ECU. The battery voltage was present at the EACU connector. I noticed yesterday after trying to accelerate rather quickly in a traffic situation that the car seemed to lose power as if it wasn't getting fuel and then it started to surge very intensely and would only hold power when I would try to accelerate. As soon as I tried to just maintain a steady speed it would seem to just drop off or deaccelerate, but it never wanted to stall. After letting the car sit for several hours it seemed OK but I never did try to accelerate quickly again, not wanting to agitate the situation. After that I changed the EACV. Perhaps the ECU has a problem, maybe it's not even the right ECU for this car? I've had this car for about 18 months without having any real trouble with it. Thanks!
