I am not familiar ith the 2.4lte engine,but it sounds like a vacuum pipe problem.Running rough,and the engine management light on with the brakes points to a breakdown in the vacuum. Have a check of the plumbing.

There are some 2.4lte experts on this forum watch and wait!

here`s where you need to look to to find your fault codes that are displayed by a flashing management light(your codes will be the first 13) https://hiace-super-custom.forumotion.com/members-guides-to-fixing-problems-f8/engine-managment-fault-codes-and-how-to-read-them-t439.htm .these buggers are prone to vacuum problems as the heat from the engine tends to stay underneath and perish the hoses,try to get yourself a little mirror for looking behind hard to get to areas.e.g.r can be blocked off but id check all the other options first.have you tried a good service oil/diesel/air filters with a good semi synthetic and some good diesel additive injector cleaner(millers all the way ).sometimes the easy options are the best to try first before taking it to a garage,as the unscrupulous ones out there(back street ones,toyota,e.t.c.....)see em as a meal ticket,holiday and christmas bonus all rolled into one

Hi , I have the 3LT 1kz-te and have blocked off the vac hose to the EGR valve with no problems, and no over heating.
The EGR only opens on idle , but give problems when they dont close properly .

I personally dont want my inlet manifold filled with dirty black exhaust smoke.

Can you just take off the EGR valve and pipework and blank the exhaust and inlet manifolds?

Yeah, just make plates and blank them off

I'd like to do this as well... So where do i start?
