[QUOTE="acf6, post: 883663, member: 3686"] Just wondering if you guys have any more knowledge to offer on this problem ive been having. Started the weekend before Christmas, i went to leave my house and my throttle pedal didnt work. Thought it was just a fluke or something, and i restarted it and went out into town and on my way back it died again. Restarted, then as i got up to speed, over about 1500rpm it was surging really bad (see first video) and couldnt go very fast. Restarted truck again, and that went away... So it was sent off to the shop. Got it back last thursday with a new engine harness and EBP sensor. Seemed to run great on the 30 mile drive on the way home, and my mechanic also put 40 miles on it and had no issues. He also couldnt even get it into the shop because the throttle pedal didnt work but i was able to drive it and park it at his shop after the tow truck dropped it off. [url]http://www.youtube.com/watch?v=xs4XoO4sNI0[/url] Fast forward to monday this week, after it had sat since i picked it up, i was going to drive it to work and went to leave the driveway and had no pedal again. Restarted, made it 100 feet down the street and died again. Restarted, made it 100 feet back in front of the house. After i got home from work i hooked up my auto enginuity to take a drive around, and it only died once, and it didnt seem to be surging again. Now for codes, this is what im getting [ATTACH=full]125028[/ATTACH] I had the same codes before it went into the shop as well. Now i found another post that i believe is from a ford service manual about testing the throttle pedal based on the codes i had [ATTACH=full]125029[/ATTACH] So i did that test, and my TPS was NOT within those values, so it said replace the TPS which my mechanic already tried with no luck. So i pull up APP 1 2 and 3 along with Vref and i can wiggle the harness and get this... [url]http://www.youtube.com/watch?v=SozX6-Ci53g[/url] So i told my mechanic what i found and im towing it back up to him tomorrow to replace the harness, but im kind of afraid this isnt going to fix the problem. I find it strange restarting the truck makes the pedal work again, but wiggling the harness cuts the voltage out. If youve made it this far...what do you think? Ive heard a sticking turbo can cause a dead pedal as well...not sure how. Or PCM related. Thanks! [/QUOTE]
