i have a 2000 ford focus se 2.0 dohc a/t ztec and swapped it out with a 2002 ford focus zx3 2.0 dohc my cuz ruined the last engine the se. so i just went ahead and put the zx3 in but now idles real ruff but goes away giving it gas i need help someone lend me your knowledgable advice
Have you checked all the sensors and valves to make sure they are all clean when you swapped in this zetec? Sounds like you might have to replace some of them. And sure you check the timing of the engine as well. Good luck~
Excellent answer by Stephen, I's start with the timing. You may want to print this, then copy at 200% or so to see it properly
AS for your original question, the Focus SE comes with a 2.0ZX3 engine, so i don't quite understand what you are asking
