Question Erratic/No Idle…Fuel Cut with FCD

Now that i'm not considered a Newbie on here anymore I'd like to get some opinions of you long-time goers.

So you're up to date, here is my build thread - https://www.rx7club.com/build-thread...orito-1065733/

And here is my newb thread - https://www.rx7club.com/new-member-r...g-out-1065315/

Now, we've go the car to start on a regular basis with no issues, although it still refuses to idle, and during driving conditions it bucks, spits, and sputters…

The timing is dead nuts, and so is the TPS. (ordered block off plates, will know more once installed)

Any thoughts would be helpful as I have searched here and via Google, but have yet to find anything close.

ALSO, at about 3,700-4,000RPMS or about 8PSI, it hits fuel cut…something I don't understand seeing as how the Rtek 1.8 is supposed to have a FCD built in. Plus the previous owner had and external FCD that I also hooked up and still cut fuel..

Just noticed also you said you had a plug in FCD along with the rtek, dont do that. Not that that is your issue, just not a good idea.

Right, we weren't aware that it was even installed until after we were running it with the new computer, do you think it would be a good idea to unplug and replug in the computer?
