Good evening all,

Since taking delivery of my '83 n/a last month i've been busy trying to get her up and running.

I replaced the water pump, timing & V-belts. Spark plugs, dizzy cap & rotor, all filters, oil and coolant.
The fuel tank was drained, and after chasing fuel issues i replaced the external fuel pump.

With new fuel pump & fuel the car fired into life straight away. However, it will not maintain idle.
The engine loses speed and stalls within around 5 seconds. It feels very rough. If i hold the accelerator down slightly, the car will run at higher speeds - enough to move it in and out of the garage at least.

After searching on here, thoughts were on a vacuum leak. I checked all lines and could not find any sign of damage.

Has anyone else faced this issue? Where should i be focusing my attention next?

Thanks - Ash

CO2 right? Adjusted the fuel or air idle screws so it runs +/- 950rpm without stalling? Checked cold and warm control pressures? Injectors spray pattern and delivery to spec? Injector seals good? The list is endless and all covered in this forums tech sections.
