I just put 6 new injectors in and changed all filters and hoses in the fuel lines. Motor is hitting on all six now but it bogs down coming of of idle. Anybody got any ideas?

All help appreciated.

My buddy Curtis had the same problem with his 77', we replaced plugs, wires, cap ,and even the rotor. NOTHING. So we got a new air flow sensor, nada we pulled it apart aha, a little tweaking of the spring and hold on where did all that power come from. There was substancial increase in power.

What turns? There all straight to my Z

The spring inside the air flow sensor?

Along those same lines, the throttle body sensor can do this as well. Bad or old sensors/connections send false information to the ECU. So it never figures out that you're trying to rev/accelerate and thus doesn't adjust the injector behavior appropriately. The tests for the MAF and the throttle body sensor are both really easy with a half-decent multimeter and are outlined in the factory service manual. Sadly, my manuals aren't available to me right now, so I can't give more details. Happy bug-hunting!

Past experience with my friends z it has been known that the plug for that air sensor(the restrictive pos in the middle of the air intake) will come lose every once and a while.

my 76 wanted to stall below 2000 rpm's, after a bunch of tinkering I changed the fuel pressure regulator and that fixed my problem....good luck!
