Cas issue
Ok i got an s5 tii swap in a s4 fc. Been running great til past couple weeks. It has developed a stumbled under acceleration and sometimes at idle. I've changed plugs and wires and ran with leading coil only and trailing coil only and could still feel the stumble. So I got a used cas and it made a huge difference but it won't cold start on it. Ive killed my battery cranking on it. Then switched back to original cast and fired right up. Runs great hot on the used cas. But I can't wrap my head around why it won't cold start with it but will run great once it's warmed up. Anyone ever had this issue before?
