well ive had an issue with the wifes truck a few times now. it will run rough intermitantly. was on the highway hauling my 20ft enclosed car hauler and she was under load going up hill and started missing, kicked the ses light on. well i checked the ses and it had a random misfire. well thismorning we got up bright and early to take the kids to an amusment park on the other side of the state and it ran fine with a miss here and there. truck sat it the parking lot for 11 hours and we went to leave and the thing wouldnt start. i had to give it a ton of pedal to run and it ran like crap, if i let up it would stall. did this for about 5 minutes and started to run fine. truck has 155k on it with a new fuel pump and filter in the last 5k, plugs-wires- 20k ago. not sure what could be causing this. do ya think its the egr? anything i could clean some sensors with to try to fix? what sensors? im clueless
