Cold start system problems

Weld the flap open in the dump pipe or take dump pipe off and unbolt the flap, remove all the vacuum hoses and solinoifs in the engine bay it's all junk, if you have a.c it will idle abit lower, just have 1 big vacuum hose to brake booster and small hose from turbo or pressure side of turbo to top of injector pump, noise will be back pressure in exhaust and exhaust gases are coming out intake, also remove egr valves if you still have them

Thanks yeah planning to clean up all those rubber vacuum hoses. I was looking at downpipes pretty pricey. Where do I make the weld to keep the flap open with out having to take off the downpipe as it will be a cut job its just to rusted, cant see the edges of the nut anymore. cheers

Do I pull off this assembly in the yellow circle and with the left over bolt that turns the flap do I attach it to piece of wire to hold it in one position?

You should be able to just weld the spring and bolt both ends to the steel plates if that makes sense, looks abit yuck but worked on 1 I did
