It's an 85 300SD (per my sig line, which I guess got cut off somewhere - sorry for not mentioning that info in the text.) I will check by blowing through the line per your suggestion. Thanks! Chris Marshall Booth <[EMAIL PROTECTED]> wrote: Christopher McCann wrote: > OK, I replaced the vac

valves JUST adjusted and fuel filters are new too. (30,000 mi maintenance just done). Will test overboost (switchover) valve by bypassing. Thanks! CM Luther <[EMAIL PROTECTED]> wrote: Bypass the overboost valve. If you have regular power, it's bad. If the power is still weak, make sure th

Bypass the overboost valve. If you have regular power, it's bad. If the power is still weak, make sure the valves are set correctly, change your fuel filters, then adjust the ALDA. Luther On Mon, 10 Sep 2007 19:10:35 -0500, Christopher McCann <[EMAIL PROTECTED]> wrote: > OK, I replaced the

OK, I replaced the vacuum line from the back of the intake manifold to the switch over valve. The old line was not clogged at all (but I have a nice new one now) and the problem of slow acceleration persists at low altitudes. No way to test the high altitude issues as I am no longer in Colorado.
