Can you rev it up in park and neutral, or does it bog down then too? If so....Fuel pump or air intake leak after maf, OR
does the speedo work? If not, then could be the vehicle speed sensor. (it will send a crap signal, the computer thinks your speeding and cuts the fuel off)
Unplug it (it's on the trans, behind the e brake drum), and if you can drive it again, you've solved for x.
Unplug it anyways, even if the speedo works...just to rule out out. Might take you 5 minutes....
