Does anyone know if grounding out the eec test port will put the car into "limp mode"? theres something wrong with the wiring in my car , i swapped out the 3.8L and put in a 5.0L HO and the dash harness in from the v6 car but the engine harness is from the v8 car and the only way it will run is if i ground the eec test port. IS this BAD, or what will happen if i keep it like this? Thanks for the help
