Hello everyone, I was driving my 03 350z yesterday and suddenly it seemed like it had lost some power to the engine. I look at the idle and it is moving up and down, about 200rpm, constantly. It looks almost like it's jittery back and forth. I get home and shut the car off for a couple hours and it doesn't want to cold start. I try and try and eventually it starts up again, though it was very reluctant, the engine barely turned over initially. I open the hood and is smells strongly of an exhaust leak. I don't think it's the fuel pump, I can hear it prime. I cleaned the MAF sensor and reset the ECU. I changed the air filter, and relearned the accelerator position. Nothing has worked. Will post a video of the idle, later today.

Has anyone experienced something like this before?
