won't idle, cannot rev up? i just completed a 6.0 t56 swap in a 92 s10, i cannot get it to idle properly,i have to feather it down and if i rev it up it will die when coming down. also cannot get it to rev up past 1700rpms it will cut out and o2's zero out. any thoughts would be helpful.
addiditions to stock engine-xr275hr-12 camshaft,matching valve springs(#26918-16), and pushrod #7955-16. computer was programmed for stock engine, car has not been tuned aftermarket, wondering if it is a tune issue or wtf???

The complete lack of idle is probably caused by that cam running on the stock tune.
However, I'm at a loss for not being able to rev it past 1700 rpms. If the O2's are bottoming out when you try and rev it, it indicates a very lean condition. I suppose if you went lean enough, you wouldn't be able to rev the motor.
Does the exhaust make your eyes water?
