It all started last week,I was driving to work and as I was coming to a red light my truck died. I got it started my mashing the gas.. It sounded like crap, I limped it home by staying on the gas..No codes that morning but when I got home I had a PO123 so I bought and replaced the TPS reset the cpu, and its the same. It is running like pure crap at about 4-500 rpm's It wont die and there are no codes. I hear what I believe to be the valvetrain rattling, but I am not sure. Oh and the ONLY way to get it started is to mash on the gas while starting in it.

HELP!!!!!!!!

sounds like clogged cat and is the rattling coming from underneth around the cat check at your tail pipe see if there is any exhaust pressure
