Guys I'm desperate so please don't view and not reply to this if you can help like so many other sites I've tried!!! I have a 1996 K1500 5.7 vortec.. I bought it from a shiester kid from the valley who did not inform me on the issues on the truck also who didn't register it in his name and totally screwed me over. There were parts missing that I can replace but I havent been able to yet. It's missing the cat,missing o2 sensor,maf unplugged when I bought it,and has a melted wiring harness on multiple connectors. I tried to plug in the maf to see what it would do but it Killed it now it will not start and when it does I have to keep a foot on the pedal to keep an idle. It ran and started awesome before even with all the missing stuff and melted harness. I plugged in the maf. It will sure try to start but it can't. When it finally does it surges terribly when I take a foot off the gas.. Please anyone with an answer help!!!!!
