Hey guys! Last night, had an issue with my Y34. Seemed to be in limp mode (wouldn't go past 3k RPM, limiter bounces) but no warning lights.
Has 132k miles on the motor. All fluids are good. I let it sit for a few hours after normal daily driving, went to go fire it up, was cranking perfectly but wouldn't fire the first 2 tries. Once it fired, I was driving for about 15 minutes, and as I was climbing a hill, possible limp mode began. Got home 15 minutes later, turned it off for 20 minutes, tried again and it was out of limp mode. It did this at 3k no matter if it's gear 1-5, Drive, Park or Neutral. Will try again later in the morning to see if it persists or was some strange incident. If anyone needs a video of what happened, I can email it you.
Possibly crank/cam sensors? Had somebody say bad fuel pump/filter, but I'm not entirely sure.
Any help or suggestions are greatly appreciated, thanks a bunch!
