I put in the new ignition module, no better. Since i just LS swap stuff for a living i think i have forgotten how to be a mechanic lol. Anyway i rigged up another fuel pump and made up some fittings to get a gauge on it. Ran strong with another fuel pump, and had 6psi fuel pressure with the factory one. So i replaced fuel pump and filter and now it runs well.
It still stalls however, it wont do it when its cold, only when its upto temp and idling. Revs seem to drop off a bit and it promptly dies after 6-10 seconds, does it like clockwork. I figured i would clean the IAC and when i pulled it out it popped apart. So i replaced that but it made no difference. Meanwhile i keep eyeing off the LS3 lol, and i think i will do a rack conversion, its been RHD converted and its a sloppy job.
Any thoughts on the idle? Hard without a scan tool that will talk to it
