Question about 2003 Jeep Liberty
Hello, sounds like you should get a compression test for the bank with number 2 cylinder. I am going by your statement about the Antifreeze smell. You could also do a fuel quality check and replace the fuel filter while doing this. Put the fuel in a glass jar and wait a day if necessary to see if the fuel separates. Bad fuel would also account for a rough idle and the smell.
The newer fuels we have today can separate and also attract water from the atmosphere. The Evap may have been a sign that the system was open to the atmosphere. Before doing major motor work, you may want to "smoke test" the Evap system. This requires a special machine some shops have.
I am curious to the condition of the old number 2 plug and if it looked corroded from the antifreeze. An alternative would be to remove the sparkplugs and crank the engine when it is cold from sitting overnight. Then observe if antifreeze or water was blown out the sparkplug holes.
I hope my solution is very helpful to you.
