I finally have my wagon back on the road after taking way longer than planned to finish the t5 swap, and unfortunately some of the issues I had before the swap have stuck around.
Engine is a '93 b230ft with an rsi stage 1 cam and ported 530 head. 16t turbo, yoshifab bracket and mamba wastegate with a cheapo amazon downpipe welded on, rest of the exhaust is currently disconnected. New ngk wires and plugs, distributor rotor and cap aren't new but are far from toasted. Adjustable cam gear but no advance or retard is set. Green giant injectors, 012 maf, k&n cone filter and an ipd silicone intake hose. Stock ecu and ezk with KL racing chips to match the injectors and maf.
On first startup the idle likes to bounce, but it's in that 600-1k range I've read is the norm. I let it warm up for a few minutes this morning, drove it to the end of the driveway, and it stalled. Took it the rest of the way to work and while it drives fine when driving normally, if you take your foot off the gas while the car is in neutral it'll stall and die. Rev it up a bit and eeeeease off the gas, and it'll (sometimes) do a bouncy idle right around 500. Stab the gas and the car will stumble and pop, roll into it and it seems to do fine. Fuel pressure is fine at both test valves. Vacuum line off the pressure regulator smelled like gas, replaced the regulator but no change.
I have an aem wideband installed, can't get it to display anything but (---), going to try hooking it to different power and ground sources and see if I can get it to read. At this point I'm thinking either my wastegate or my ecu has failed, anything else I should mess with while I try to get the wideband working?
