So i came home today, and wanted to clear the snow of the driveway so i decided to move the ES, however the car was idling terribly rough and the VSC and CEL light is on. I dont think the CEL is flashing, i think it was solid. The car also runs really rough, does this sound like a knock sensor? Any ideas would be appreciated. Time to go sleep nightshift suckssssss.

My parking brake light is on most of the time now. It suddenly started to turn on when the temperature started to drop at the start of this winter season. I have no clue what it could be, any ideas?

I also have my rear light display light on in the dash, but apperently that's because the aftermarket bulb I used doesn't have the same voltage flow as the original OEM ones...

^^^^^
Are You serious??

Anyways i went and pulled the codes today and 3 of them came up.
0300, 0302, 0303

0300

Random cylinder misfire detected

Large vacuum leak
Fuel system concern
Ignition system concern
Engine mechanical condition

0302

Cylinder 2 misfire detected

Large vacuum leak
Fuel system concern
Ignition system concern
Engine mechanical condition


0303

Cylinder 3 misfire detected

Large vacuum leak
Fuel system concern
Ignition system concern
Engine mechanical condition


So to my knowledge, the culprit isnt an o2 sensor or a knock sensor.

Another main issue is that it will not go into 4th gear, darned thing is revving at 25 hundred at 40 miles per hour.

Any ideas my way would be greatly appreciated, im trying to figure this out on my own with your ladies and gents help, as i dont feel like taking it in anywhere. I want to do the manly thing and fix it myself lol.

^^^ i was thinking that, i bought the car with 122k on it and it has 126k on it now and no i havent changed them and i didnt see anything in the service records saying that they were done. But why pop up out of nowhere though thats what im wondering.

The not goign into 4th seems like a seperate issue.

Cyl 2 and 3 are on different banks (diff sides of the engine), so it is liekly a big thing that happened. IF your plugs do have 126k miles on them, a little problem can turn into a big one like this.

Check the Intake Hose to see if it's split anywhere. It's also possible the MAF sensor can be dirty an not correctly reading the air causing a misfire. Thats an easy job to clean one. You just need Electronics Cleaner.

Well i just finished installing all 6 plugs, and the back ones were not fun at all. However its still the same, the car runs the same. i can honestly say i love my GS, owned 3 of them drove 200k miles between the 3 of them and never had any issues.

This car has been very well maintained, i just checked my records and the plugs had been changed at 90k with denso iridiums. I bought it from the lexus dealer here and i have every record for the car since new. Charcoal canister has been replaced at 90k so that rules that out as well.
