Hey Guys, I'm pretty sure I have narrowed my problem down to the Lambda ECU. My Frequency valve will not come on...well.. ever. Thanks to Rich A I have been able to test all the parts of the system. The car runs no differently with the Lambda ECU disconnected or the frequency valve disconnected. I'm surprised how well it runs without the Lambda system but I want this fixed. -Jumped RPM relay contacts 87b & 30, 12volts at frequency valve-checked,<br> -With key on, tested pin #8 at Lambda ECU connector-checked 12volts ,<br> -All grounds cleaned,<br> -Ran 12v directly to the frequency valve and it worked<br> Before I buy a new ECU I just wanted to see if there is anything else I can do. keep it real Dave 6286 [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
