Well, I check the alda line, it seems fine. On this car is a little different than the 91. It comes out of the intake, goes to a Y, one of the Y's go to the ALDA, the other Y goes to a pressure sensor by the battery. Does not have the cutoff switch in between. I pulled the codes and it had one for EGR actuator/transducer something or other, one for rack position sensor, and one for starter ring gear sensor. Cleared the code for EGR, but no matter what I did I couldnt get the other 2 to clear, even after unhooking the battery for a while. I also noticed while idling, if you run the engine ad various RPM, the flap deal on the turbo outlet never moved at all. On any other 2.5 I have seen, it seems to move back and forth at various times if you rev it up and/or down while sitting there. No code set for that but something doesnt seem right. I do know when my other one I had, if you had any sort of vacuum leak you had zero power. I suspect there is a leak somewhere.
Anybody know how to test all those switchover valves, and vacuum transducers/actuators whatever they are over on the passenger side?
