By using that plug you get a code 33 and ONLY a code 33. Without the plug you get 2 or 3 more EGR system codes. The code 33 will not set a check engine light on cars that actually have working ones. One of the other codes WILL. With our cars it's moot, but in the factory equipped Mass Air cars it can be an issue. Even if you did a MAF conversion with a later ECU it won't show up in a CougarBird as far as I know.

My Thunderbird is converted to MAF with an A9P processor. When I unplugged the EGR solenoid and EVP sensor the computer illuminated the check engine light. The resistor plug shut it off. Now it just shows a code 33 with no check engine light illuminated.

Before you start disconnecting everything check out a book- Ford Fuel Injection and Electronic Engine Control by Charles Probst. The book is written in plain English- easy to understand even for this old guy. The book is for 88-93 cars. It will save you money and teach you what the EEC does. 88 and newer cars have computers that "learn" how the engine is operating and can adapt to how the car is driven. All parts are necessary. The EEC operates at 120 times per second to manage fuel injection, timing, etc.
