    To much fuel

    My 82 continental is getting lots of fuel, and i was wondering how to test the map sensor and the coolant temp sensor. Also if anyone else has any suggestions. Fuel regulator has been replaced and injectors cleaned and tested pretty good

    Not familiar with EEC III but here’s a couple things:

    On the ECT - assuming it’s the same as the later ones, check the resistance between the two pins compared to the resistance values found at the bottom of this webpage: http://www.myo-p.com/Ford-EEC/EEC%20...e%20Sensor.htm

    On the MAP, you might be able to unplug and see if the system defaults to a usable value that makes the car run but maybe not run well. Should be enough to tell you if it’s the problem or not.

      I'm also not real familiar with EEC-III. Beyond making sure you have vacuum at the MAP and no vac leaks, what might help is picking up an engine and emissions diag manual. That will have specific test procedures by symptom for all sorts of problems.

        I unplugged the connecter to the coolant temp sensor and the map sensor, it ran poorly when i did both, i was wonder is my egr valve could be the issue, also i do have those books around here somewhere

          if the EGR is stuck open it will run all kinds of messed up. I think 82 has a cooler under the valve. Would be worth pulling that to make sure the valve can completely close and verify its not getting vacuum with the engine running.

            Just got time between saving a corvette and buying my 94, was looking for bad vacuum hoses and the second picture that isnt the tv cable bushing is it? And the first picture thats the egr cooler and on top is the egr valve right?

              Yes and yes.

              It looks like your TV bushing is missing. Need to get one quick! I would not drive it without a bushing in there, or at least wired up so the rod doesn’t fall off the stud. https://www.ebay.com/itm/FORD-MUSTAN...EAAOSw~vpZ~h8U

                  You can check if your EGR valve is getting vacuum properly by putting a vacuum gauge on the vacuum line from the EGR solenoids.
                  If you have a similar EGR setup as me, the EGR is controlled by 2 valve cover mounted solenoids, control & vent:
                  They are the 2 middle ones and look like this:

                  I'm holding the line to the EGR valve.

                  If you suspect the EGR valve, you should take it off and test if it's sticky or leaking. I found easiest to spray carb cleaner or whatever into the larger port and see if it leaks past the piston.

                  When you get your TV bushing in place, you could go for a drive with the EGR valve unhooked, the line plugged and the EGR solenoids unplugged. If you car is running that bad, were it the cause, it should make a difference.

                    Got the cooler and egr valve off, egr valve moves freely and no brake clean comes out the valve, on the cooler brake clean goes in on side and come out the other.

                      are the vacuum lines to the MAP good? Does the EGR get constant vacuum when the engine is running? It should not.

                        I do have vacuum to the map and the engine ran worse when unplugged, ill get everything back together and check for vacuum at the egr, on start while idle it should have 0 vacuum?

                          correct, 0 vacuum at idle.

                            It has no vacuum at idle, for a better example of what it does, it will drive fine down the highway, then sometimes stalls a stop signs (the fuel regulator fixed most of the stop stalls) and in reverse it like to stall out

                              The bushing for the EFI cars is the same one for the carb/CFI cars?
