Default Engine Missing

Hi all volvo people I've just been removing things from my 940 ac condenser ect, front chassis weights,radio charcoal canister and iac valve. I've blocked of vacuum ports on manifold and iac and also blocked of the hose coming from intercooler piping to the iac valve and now it's got a misfire any suggestions also I've wound the little adjustment screw to make it idol. Any help would be great

Maybe some of those "useless" parts serve a function?

Seems weird that it would plenty of people out there remove the same things and have no issues. I may have bumped something could even be fuel pump

Seriously... find that engine.

I put a bell on mine. I’d retrace your steps part by part until you find the culprit if you had it running well.

Well you gave these guys the chance to rick roll you and they took it.

All of the things you disabled on your engine may have caused a large vacuum or air leak. Air leaks can make the engine misfire. I don't understand why you would remove the idle management and charcoal canister. They are things that help your engine run better and pollute less.

If you removed the charcoal canister how did you vent the fuel tank? Did you also delete the vacuum source to the fuel pressure regulator? It probably needs that Idle air hose reconnected to the intercooler tube even if only to run a ball valve to control idle air.

Too many variables. Check vacuum readings at idle, check plugs and wires

I've heard and read that this is a thing that some people actually do and always wonder what they want to achieve with this.
Maybe OP can explain?
