Is there a pic floating around here somewhere that shows where the hose to the egr connects: One end on the egr....the other end on some mystery thing. The guy I bought it from pulled the hose....i want to reconnect it and see about better gas mileage. Thanks
To all you guys removing it saying it is fine to do so, are you just assuming since the engine runs with no probs that everything is A-ok or are you actually reading a dyno sheet showing the air-fuel ratio so you can watch your mixture go lean when the EGR should be open??
I have made several posts about how removing the EGR without disabling the function in the computer would cause part throttle detonation due to advanced ignition timing.
It turns out this is wrong, and I want to get the correct info out there.
The computer does see when the EGR is not functioning properly. When this happens the computer enters an alternative strategy, which eliminates the fuel and timing compensations that are usually made when the EGR is working.
I have yet to figure out all the details on the "Alternative Strategy", but I think it safe to say that Ford would have made these settings rather conservative.
This was pointed out to me by Joel5.0 from MustangForums.
I have confirmed with the Ford EEC-IV GUFB Manual that this is accurate.
Here is a summary of when the Failure Mode Strategies are used.
