Injector flow test FAIL ?, Troubleshooting lean condition Options

[jim-c]

Im working on my recent 914 purchase. 2.0L engine. D-Jet ECU . Intially the engine would fire right up and idle smooth at 1000 rpm. Unfortunately it didn’t want to rev above idle. I could quick pump the throttle and get it to rev but it was undrivable.

I have an AFR gauge and it shows dead lean when i try to rev.
I did a flow test on two injectors ( all 4 are new ) . I have 28lbs of FP .
Full throttle and crank for 15 seconds yields 2cc per injector. Supposed to be 7 ish.

Any ideas ?

Nice new harness, MPS holds vacuum and has correct impedance readings.
The balance of sensors check out okay with test procedure. Fuel pump holds 28 lbs steady and pumped a quart of gas within 30 seconds .

Here’s an update /solution for my problem. I pulled the injectors and tested the output on the bench. Amazon sells an injector triggering device for 30.00 . My injectors were 80 percent clogged from sitting, i guess. I flushed out little bits of rubber. I got the car started and it idles.

My sincere thanks to everyone that replied.

@Van B At-home injector flow testing? Measures flow or just squirts? Probably the latter.
