Hey guys. I've been lurking for a while and have found some really great info on this site.
I've had a 2000 250 7.3 2wd 6 speed manual for about 4 years now. I am very familiar with the hissing sound the EBPV makes when it's cold out.
Within the last year my valve has started opening and closing in about 2 to 3 second intervals, and just keeps cycling. The valve will operate when I'm trying to accelerate or when idling. It's a real pita when I'm trying to get up to speed, and it's pretty dang dangerous when driving on ice or snow. The thing won't settle down until it's well into operating range either.
I noticed this summer the valve would open and close even though the temps outside were pushing 80 degrees F. After I tap the brake pedal it would quit and then do it again 2 or 3 more times.
I have cleaned and inspected the EBP tube a few times, I also installed a new International sensor. Found it on ebay for $5 brand new.
As a side note, I also did the Stancor mod a few months ago. Though Stancor doesn't make the part anymore. Now you get it through White/Rogers.
Does anyone have any insight on what I should look for or test to get my EBPV to operate normally? I don't want to delete it, I just want it the way it used to be.
Thanks in advance, Bill.
