Actually it is a 1985. Why does my engine idle then sputter when I give it gas?

(1990 Volkswagen Vanagon)
I am chasing a possible vaccum leak/air flow or fuel problem on my 1985 VW Vanagon. The problem started with some uphill sputters in second/third gear. Now when I give throttle the problem exists at certain RPM? The engine idles then seems to get to much air or a gas flow issues. I am not familiar with the digi-jet fuel injection, I realize there are a lot of sensors and lines. I have not run fuel injector cleaner through the gas, yet. I have replaced air flow meter box and S shaped boot from the throttle. There is a whistle coming from somewhere when I engage the throttle; hard to tell where but seems to come from around the throttle?? Or even somewhere on top of transaxle??? With engine noise it is difficult to tell...wish I had a doctors stethoscope. Any and all assistance is highly appreciated...thank you for your time and consideration. Mateo

Sounds like its your distributor cap and rotor to me
I think you need a tune up
Change spark plugs, plugs wires, cap and rotor

Still sounds like there is a whistle when I engage throttle on the engine, can't figure from where. Exhaust manifold on top of heads(3&4) leaks smoke when hot, gonna check gasket but, that whistle is coming from somewhere else.
