Engine surges when starting cold. Most recent problem was a faulty oil pressure sensor, which was replaced. Surge still persists. Once engine warms up a little, the surge goes away!
This (car) engine has always been extremely dependable!

Check the electronic coolant temp sensor, and air intake temp sensor.
