When I turn off the cel with the obdII scanner the van runs better, but after 100 miles or so it comes back on and its running rough. In my original obdII scan, when I first bought this van a few weeks ago, the po120, po325, po302, and po702, po703 were all lit up, I cleared the codes then and it didnt light up again for like 200 miles with only po325 twice and po302 once.I dont want to do a knock sensor if it is somethging else. Could the initial code po120 tps still be the culprit but it hasnt come back on yet for some strange reason? Thanks guys, I am a girl and need all the help I can get, im alone on this one.
