Thanks for the reply. The accordion has been replaced with a Jerry's gaskets one. I do have a scanner and it throws no codes, but has thrown a lean code left bank a few times. My BLM and INT on the left side is around 150 as well, and the right side stays around 130. I jumpered all the injectors and heard a click for every one too. Although my scanner is saying the vacuum at idle is 0 kpa, but I'm not sure if the car should be giving me a reading for that. TPS and MAP voltages seem fine. O2 sensors are new and cycling like they should in the scanner, although they do not read evenly, and cycle slightly offset, I could not find anywhere if that was normal.
