i've got an 06 that i've owned since it had 3k on it. i have averaged anywhere from a low 18mpg(city driving) to a high of 23.5mpg(highway). i just went over the 70K mark and out of the blue, i cant manage anything better than 15.5 highway. i"ve cleaned the air filter and reset the ecu and nothing has changed. what i have noticed is the load percentage for the TPS is reading around 23%-24% at idle! that seems extremely high for idle. i thought that it should be reading 3%-5% at idle. can anybody measure thier load percentage for me so i have something to compare it to? HELP! i've gone from 320miles per tank of fuel to 200! this is killing my wallet!
