1974 1.8L engine fast idle then stalls, Fuel injection issues Options

[tshih914]

My 1.8L 914-4 with stock Bosch L?-Jetronic FI after being stored several years started to develop a hard to start problem. When finally started would stall when I give the gas pedal any input to raise the revs. I suspect there was some kind of intake air leak and while fiddling around had a backfire which blew the AF meter which I had Pelicanparts repaired. After replacing the fuel lines with the stainless ones from Tangerine Racing and flushing out the fuel system with Techron the engine started to run normally for a short time. Now the engine can be started and fast idles at 3000 rpm but again any input to rev up the engine results in stalling. The idle adjustment screw at the base of the throttle housing is fully closed. Any suggestions on how to fix?

@wonkipop What alerts me is the no change in idle with the snorkel completely covered. I made that video because this thread reminded me that I should post this up for future reference.

Let’s confirm connections first and then see what’s working and whats not.

@tshih914 , the high idle started after you made repairs to the car? You said in your original post that it ran normally for a bit. What happened between then and now?
