honestly im not sure, ive had a weird idle problem since day 1 actually.

all my air/fuel ratios are spot on while driving, decel, accel, wot, etc.

if i am sitting in traffic, or at idle in the heat, i can watch my Air/fuel ratio start leaning out to about 18, and then itll bog down real quick and almost rev itself back up and then settle to an air/fuel of about 13.5-15. give it another minute or so and itll start leaning out, bog down and rev back up

i havent been able to figure out what it is, so i figured its either A - the maf being bad/getting heat soaked at idle and throwing a bad reading
or B, the TPS is bad and it is having a hard time finding out where it is sitting

p.s. if its a cold night, ill never have the problem and the car will idle perfectly.

any input? haha
