Group, Okay, either I'm the unluckiest guy I know, or Josh's car just plain hates me. For the second time, I have run across something I have never seen or read about before. But, the frequency valve is now working!! :-) After many hours of trouble shooting and pouring over the wiring diagram, I finally figured it out. It was the RPM relay. I ordered a new one, but decided to open up the old one, just to look inside. What I found was a first. The little coil inside had broken loose from the contacts on the circuit board and was moving just enough to 'not' make contact when the coil closed. Hence, no Lambda and hence no FV. I re-soldered the connections and it is now working 4.0. Now, here's my new question. The relay was actually designed to mount upside down in the relay compartment, causing the little coil to put all its weight on those two soldered connections. (the circuit board only fits one way into the plastic case) When I reinstalled it, I mounted it so it was right side up---does anyone see a problem with doing it this way? (Elvis, I'm counting on you to have the answer) Mike TPS & BB 1630 ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
