Yes, I know what the differences are. And I wasn't talking about EEC-IV in particular, OR the returnless system (SINCE THE PERSON WE WERE TALKING ABOUT WHO POSTED THIS TOPIC, SAID HE HAD THE SYSTEM WITH RETURNLINE).
And just so you know, my Mustang did NOT have a MAP sensor (post-'89), and I was only using that car as an example, since that was the car that I first observed this condition. And I work on tons of cars every year that utilize this same aparatus on them, although they aren't all equipped with this. So, Mr. Genius, if you say I'm wrong, then why don't YOU tell everyone what the purpose is for the vacuum hose on the fuel pressure regulator on these cars equipped with this, since the ECM can compensate for everything just by changing the injector pulse width? Tell why they felt they needed to influence fuel pressure with a vacuum source.
You don't have to believe me. I really don't care if any of you do. Some of you Contour guys here are so stubborn, and think you got it all figured out.
That's why sometimes I get so sick of trying to help out here on Contour.org, because of people who just sit and piss on all my experience and act like they know everything there is. All the car forums just seem to have so much attitude in them, and they just tend to bring out my bad side lately.
Sorry for the stupid rant, I just had to get it off me, and good luck, I hope you guys figure all your car problems out.
