I have a 95 Lexus LS400. This morning driving to work and the car just started to shake hard. I noticed a big cloud of smoke come out, and the check engine light started flashing. I lost alot of power. I drove it on to work. During my lunch, I drove the car down the road. I had a lot of lost power. I pulled over and found white smoke flowing out of the tailpipe, with small amounts of gas spraying the ground. The car smells bad of gasoline. My check engine still flashes for five minutes, then becomes steady. What am I looking at?

It sounds like a fuel injector is shorted causing he PCM to open all fuel injectors at once which is common. I would remove the injectors to test them using this guide.

Please go over this guide and report back.

I checked the oil, and there is gas in my oil. I also added anti-freeze and found the mixture to be milky. Does this still lead to the fuel pressure regulator or injectors? I havent got the codes checked yet, cuz i'm scared to drive the car and create more damage.

Gas and coolant in the oil crankcase is no good-Sounds like you need to have it block and pressure tested to rule out a blown headgasket, cracked head or block and intake leak-causing both to be in the oil
