I posted a message back on March 25, 2003 on this topic
and was glad to receive two diagrams from Tony (Thanks Tony) to help
Unfortunately, we still have unanswered questions. For those of you
who have access to Mitchell's, if you look at Fig. 3 $ 4 of the 5.0L
V8 diagrams (200818 & 200819), both illustrations show two vaccuum
lines from the canister, one "to fuel tank" and one to the T.B.I.
My truck has a third (white) vacuum line that is at this point
unattached. Does anyone have an idea where this unidentified line is
SUPPOSED to go?
The turck idles rough, the Oil Pressure wavers while idling, and the
check engine light comes on. I believe these are all related, and
hope that sealing this vacuum question will solve them.
