I do not but I can't imagine on the bolt for the caliper to the bracket that you need to be that specific. Just make sure you get them as tight as you can within reason. Do not go crazy tightening them down.

Here are the areas I would look at first. Code 31. Is your (Air flow meter signal) I would remove and clean out yoru maf sensor. Use this maf cleaner.

Code 13. is your (Rpm signal no.2) This could be in relation to your code 31. But it is hard to determine. If you havent yet get your timing belt and components changed. Install new spark plugs, dist cap & rotor. Basically a full tune-up. This is as far as I can go without looking at the car. Hope this helps

Thanks for the tips! 
All the stuff you just mentioned has been done,and was done by a lexus tech on the side. However i was not impressed by his work. He did not change my crank seal because he said the gear would not come off and he was scared to heat it. But then he assured me it was not leaking only seaping. Im not the best tech in the world obviously,because i cant fix my problem.....yet! lol. However that really dissapointed me on his skill level. So now i have to wonder if the belt is on correctly or not. Furthermore this problem existed before all this tune up and belt proceedure. Is their a way to test the afm?

There should be absolutely NO leaks coming from that seal a seep is just as bad as a leak. I would get that replaced. Your maf sensor fluctuates from 0V-5V it moves up/down due to load,temp,elevation etc... I would replace the sensor just to be safe. Check your hoses for any cracked or looseness. Any lose in vacuum will cause issues as well.

Thought I'd give this a try.
My keyless entry doesn't work 100% of the time. Sometimes it'll work, sometimes it will not. I haven't checked any fuses or anything of the sort. Changed the battery on the key, and it still does the same thing. This started to happen around November. Changed the car's battery back in December after the alternator and battery died.
Any ideas?

Whats the year and model on the car? Sometimes the transponder in the key can wear down and have intermittent problems. Constantly locking/unlocking with the key can wear down the contacts in the circuit.
