so i swapped my gsr into my 95 ls today. the gsr motor is a 95 as well. im using the gsr engine harness which plugs right into the ls plugs. before i wired up vtec, iabs and the knock sensor, i wanted to start it and make sure it started. it did, but it was def in limp mode. will having those 4 wires not hooked up cause it to run in limp mode? any suggestions, im gonna try and wire up all that stuff and see if it goes away., any suggestions on things that i could have done wrong? im using a obd1 p72 ecu too

 

Um check the codes. Knock sensor will make a car run a little rough but driveable the rest of the vtec codes nope wont really effect much just a slow car
