This is a 2003 6 speed touring. I can make it to work fine in the morning about a 5 mile drive. On my way home it normally messes up and hits limp as i exit the off ramp and come to the light. I have been as far as a 12 mile staright shot as long as im on the highway it is fine but as soon as i start to stop and go it will go into limp mode. i have a brand new pedal and sensor assembly on it. i have tried 2 throttle bodys. The kicker is it seems to do it when its hot or at operating temp. I can check volts when its cold at the pedal sensor and its around 5 volts as its suppose to be. Once its hot and in limp mode the volts drop to around 1 volt. Im sure this is the cause, but what is getting hot and causing me to loose power supply? The car also has a evap code but i dont think that is the cause for limp mode, i will tackle that later on. I have to limp the car home from work when i exit as i stated but after it sets a few hours its ok for a few miles around the block. Once its hot the codes come right back as soon as i reset them and start the car. i have done all the relearns as well. I have a friend at nissan but he has not helped much besides giving me the trouble shoot tips. Where should i look from here guys, any idea what would get hot and mess up.
