Morning. My 05 Gx470 was having major issues holding idle after start yesterday. Temp outside was less than 20F. I could not accelerate over 1200 rpm and there was a dead spot until about 3000. Rpm. It felt like it was in limp mode. Once warmed up worked perfectly. I just recently put the secondary air bypass kit in and it has been working perfect until this issue. Please help.
