Hey guys,

just recently bought a hiace. When cold it has a misfire in cylinder 2 at idle, it also has a slight misfire or hesitation when under load and is worse when it colds and slightly noticeable when it's warm. It has spark, fuel, no vacuum leaks and good compression. It doesn't have oil in the coolant or vice versa. I took it for a drive up the range and could only make it up half way as it started to buck pretty badly when under extreme load. Luckily for me I drove back down the mountain and drove home.

I have replaced the leads, dissy cap, rotor button, fuel filter, air filter, checked plugs(which are fine).
