Hi, i'm new on this forum and i have a misfire problem on my Lexus is200 sport V6 2001, that is making me going crazy and desperate.
When i first drive the car in the morning (cold engine) the car drives fine with no misfire problems, soon as i stop and turn it of, with the engine already warm, and turn it on back again few minutes after starts the misfire.
I read the codes with a obdII and is always the code 1301 ( misfire cylinder 1) and sometimes the code 1171 as well (bank 1 sensor 1 to lean).
I've changed the spark plugs, coil packs, check the air pipes and still not sorted.
Please any one can help me???
Thanks in advance.
