So, while I'm at the process of cleaning out the injectors I clean the banjo fitting- good. Then I check hoses from the Alda to the vacuum amplifier (blue disk shaped thing) and they let air pass okay. But here's the strange thing- with the "Y" adapter that attacheds to the ALDA disconnected the car drives equally slow. I have 2 2.5's -- this one has less power (although has gotten better with the purge) If I disconnect the "Y" at the ALDA, I should see some performance difference, no? What to check next? John, I don't know why your ALDA would be connected to the vacuum amplifier (normally this is for the auto transmission modulator)! From the banjo on the intake manifold, the pressure signal should go through a normally open electric valve (part of over boost protection) and then to the ALDA. On yours there may be a tee in the line for an electronic sensor/monitor. For a GOOD test, you should run a pressure line directly from the banjo fitting to the ALDA. Please review your connections and try the test I mentioned. Jim Friesen Phoenix AZ 79 300SD, 261 K miles 98 ML 320, 136 K miles
