Nothing personal player #3, but if this is the best you got you need to stay home too.
'The mod though wouldnt count as a vaccume leak though. The PCM knows when it opens the EGR valve, and the O2S would moniter the change at the same time, so the PCM wont throw up a CEL. It only knows if its getting extra O2 if there is a leak after the EGR valve or if the valve is stuck open.'
I can find so much wrong with that it's not even funny. Just where do you guys get this stuff??? No wonder so many of the cars this site have so much trouble. You're hopelessly lost.
Save one of those whistles for me mcgarvey, these boys are flat tripping me out. They should consult Webster's and define the 2 words VACUUM LEAK and see if they can figure out what that means.
On second thought, maybe they can't. HOO boy...........
Here goes AGAIN. FORD........you remember them right?..... defines unmetered air as ANY that has not been measured by the MAF unit. EGR does not count because it is NOT AIR, as soon as air goes through that opening it IS AN UNMETERED VACUUM LEAK. If you can't grasp that you need to stay out from under your hood. Your car will thank you for it.
you're wrong. i broke the EGR tube right at the cat right after i got my car when i was punching out the cat. i let that go for a few weeks before i replaced it and it never threw a code and the car ran fine. Last year, the gasket right after the EGR valve had a hole in it and that did throw a CEL. Also, the O2 sensor DOES know when the EGR valve is open. O2 sensors dont moniter oxygen, they tell the rich/lean by temp, and nox are created at high temp. how do you think the EGR valve knows when to open?
