I have a 92 stang that I did the complete 88 TurboCoupe engine swap! Followed stinger's instructions and re-read it about 400+times. I have every EEC-IV pin-out diagram ever made and had a guy who builds XR4TI's look at my car and he can't figure out the problem. I finished the swap about 9 months ago and almost every day I play with the car and still it is exactly the same, it starts and once warms up begins to miss and runs rich as hell. I have replaced every sensor, meter, computer, checked and double checked the wiring and spent $1721.82 dollars so far chasing just this problem!!! I am about to give up and sell everything. Anyone have any issues with there 92 with a swap or is there anyone out their with a 92 that got this swap to even work?? So fed up.
P.S.
The mustang was running perfectly before the swap and so was the turbocoupe.
