2003 Ford Explorer 4.0l flex fuel awd
So my 2003 engine timing chains gave out, picked up a 2004 Explorer and swapped the engines. I used the 2003's spark plugs (2004s were bad), intake, injectors, valve covers, exhaust manifold, and harness.
The 2004 ran fine, had a bad transmission 100k miles.
Are the spark plugs different? No codes or cel. Just idles really rough, accelerator pedal is laggy, like revs up a bit, then a lot. Have to give gas to start, if not on gas will die after about 10 seconds. Spark plug wires are wired correctly.
Any sensor that comes to mind that I didn't plug in? Not sure where to start, only diagnostic tool I have is torque pro app.
