Bostig Idling normally, sputters and dies upon acceleration

[surfdistortion]

Hi,
I own an 86 weekender with a 2.0 zetec bostig conversion. I am admittedly not as knowledgeable as I should be and would like some help troubleshooting.
I've owned the van for about 9 months, completely trouble free with regular maintenance.

Currently, the van is starting and idling normally, but stutters and dies when the throttle is engaged. Fuel filter has about 3000 miles since its been replaced, as well as the air filter.

Any help with narrowing down troubleshooting would be greatly appreciated.

I'd gather all the info you can and open a ticket on the Bostig website.

X2 on that one. Lots of possibilities, but really the best person to diagnose the most accurately would be Bostig. It is likely something simple though.

Fuel filter might be clogged, press the throttle for more fuel and the engine dies.

Need more information to be more helpful. Do you have the SCT-3 for monitoring? Or the UltraGauge II?
