Default 91 telstar tx5 turbo. Vaccum problems maybe

Just had the head rebuilt. And turbo seems to have alot of lag, when accelerating a little harder the car isn't smooth accelerating it really rough and jolty kinda. And also when overtaking its struggles to rev to 4000 and has like a miss at high revs.

I'm thinking vac leak or intercooler leak or EGR valve . Anyone have the diagram of the vac . And has bad idle sometimes. No bas idle

Check the throttle body rubber for splits, notorious for splitting

Cheers mate. Yeah that's all good. That's fairly new . A year new anyway. But no splits or cracks in hose.
