The engine will rev up initially but then stall until it's warm. Then it will idle roughly until something happens where it just acts like the ecu is trying to kill it, with the rpm dropping down to like 300. It doesn't die though, it just barely recovers in time and goes back up to around 750rpm, or whatever it's normal is. I tried adjusting the idle screw in the TB, and unplugging the pcs vacuum hose to give it more air to simulate the cold idle increase valve that it doesn't have, but that made it run even worse. When I open the throttle, it bogs and doesn't rev smoothly, and then if I hold it open above idle, it cuts out and drops off until I let it close, then it goes back into idling shitty. Normally that would tell me map or tps, but I've substituted both, by changine the entire TB. Ugh! No codes except for 20, the electrical load detector thing. I don't have any idea wtf that is. I want to try a 95 ls TB, since that's what my ecu is from.
I should note that I don't have the exhaust fully connected, just the manifold and downpipe. But still, I have never seen an engine run That bad because of just that.
