U235a4

I have the same problem with my 01 is300 it started around 35-45k miles but I now have 70k. my miss hits around 4000 till about 5000 and it's like a wall aka rev limiter and once its past this point it good. no mil light, good milage, shifts good I'm thinking wires or coils but it could be something else I just hate to take this to a garage and get screwed when it's something I could fix if I knew what it was. Also I want to add I notice it misses worse on dry days aka like static discharge and seems better on humid days altho still misses. I thought fuel also but since it seems to pull good from 5k to 6k I can't seem to think it would be a fuel issue aka injectors or pressure.

Thanks for the reply I don't know if I'm going to lower the car just a thought but at this point getting the car to wear right will be nice. do you know what the numbers are I was at his site signed up but I never get a activation email. as for tires I was going to thinking about using BFG g-force T/A KDW 2 215/45-17 F and 245/40-17 R other brands using the same size are Dunlop Direzza Sport Z1 or Bridgestone Potenza RE-01R but I like the price of the BFG's

I did a few searches and didn't find what I was looking for or ran into a closed door ( alignment setting via tony( couldn't sign up)). #1 what is the stock rim width 7 or 7.5 #2 can I use a 245/40-17 rear on the stock rim #3 what is a good lowing kit for a drop of .75"-1" #4 does anyone know the cussed numbers to use for the front or all around so I'm not wearing tires out every 20K Thanks for any help
