Hey guys so im having a bit of trouble here figuring out the problem with my 92 ls400 just bought the car 2 months ago. so i was driving it to work a week before and my engine died at a light figured it was because of my subwoofer cause a short. so i waited 2 minutes started it back up drove it too a friends parked it let it run for 10 minutes didnt see any issues drove too work fine. 2 days later was driving it onto the highway felt a little power loss as i was accelerating around 2000rpm after 3 it was fine so i continued driving got too the mall let the car sit for a couple hours came back out started it let it run for a bit then drove back towards home engine died completely even with my foot down then wouldnt start back up towed it back to my house let it sit for two days then tried to start it it started up it started but now idles below 1000 rpm revs up fine as the rpms kick back down it shudders a bit no idea whats going on also coolant light just came on
