this is kind of a dumb question, but when your reading your fuel pressure, should it be at 39 psi with the vacume line on or off? i looked in the haynes manual and searched here but no luck.
the EEC can adapt ~ +/- 25%. you dont think it will adapt!?giddyup306 said:To a certian degree yes.
ok, i gotcha. - i think that might fall outside the adaptive strategy parameters. LOL.giddyup306 said:Don't get me wrong it will but with aftermarket AFPR's around you can have pressure as high as 120 PSI of fuel pressure. That's the exception I was talking about.

i was thinking in terms of the numbers 88 GT 5 oh posted - he might be 5-6 psi high. i think we would both agree that the puter will adapt to that.
(you threw me for a loop with your post as it would pertain to this thead).
as you were.giddyup306 said:OIC. I thought you were asking a question. I thought you meant to type a ? instead of a . Sorry about the confusion. Carry on
man Michael, you think of everything.Michael Yount said:Practically - it probably wouldn't make a big difference; but without it being plugged (just hold your thumb over it) you've got a pretty good vacuum leak which impacts idle speed - that impacts alternator output which might impact fuel pump performance; and reduced idle speed impacts how the engine's using fuel. How big will those impacts be? Probably not big - but why wouldn't you cover the vacuum line with your finger while you're taking the reading?
Cause I was using one hand to adjust the pressure and the other to hold up the hood (no prop rod).Michael Yount said:- but why wouldn't you cover the vacuum line with your finger while you're taking the reading?
