I have a 1999 lexus es300 and i am throwing a few codes out can anyone help p1135 p1155 p1351 a random misfire code and a 2 4 6 misfire codes any help would be great

 

P1351 is likely the only code you need to worry about - it has to do with the vvti sensor or cam sensor on bank 2... That's why 2,4 and 6 are misfiring likely... Most likely just the sensor... Replace, reset and drive... My bet is that takes care of it all...

 

I guess cleaning the oil control valve screen would be a better first step, I just remembered that code can be set by a non functioning vvti solenoid...

Basically, find the vvti actuator, pull the banjo bolt that goes into it, inside is a cone shaped screen, remove, clean with brake clean/carb cleaner, reinstall... There are two on your motor, just do both while you are at it...

 

I tried the cleaning to no avail and replaced both sensors same code still comes up but only after the p1135 and the p1155 come up ig. Clear the codes those come back immediately

 

OK that's good, those are o2 sensor codes .. Check fuses and if ok, chances are those o2 sensors are bad...

Assuming the 1351 and misfire codes didn't come back???
