Car wont idle (wont stay on)

It's hard to tell in the video, but it seems ya may have a vac leak somewhere. Have ya double checked all your lines and made sure they're where they should be? As well double check the torque on your EGR valve.. I forgot to tighten the bolts on the one to the intake and it idled really rough and wouldn't stay running until I realized it and tightened it. Was fine after that except the loud knock.. different issue though lol

yup checked vacuum line 5+ times lol as i had this probles for about 3 weeks. i'll double check the egr torque. i'm sure i tightened them though

Might want to check your AFM. If you've gone through all the vacuum lines (and there are a BUNCH of them, some tucked away and hiding), check your AFM connections and the I/C piping for problems.

yup check afm and ic piping already .. probably one of the first things i did because i thought the problem was afm related.. but it isnt. there arent anycodes other then 52.. which is my KS.. which i fix already.. i just need to rewire the front one. but a KS shouldnt cause this problem though..
the next thing i might look at is the tps.. after that.. im stumped

bump any other suggestions?

Have you checked that tps yet? How far off was it, or was it dialed in correctly?

not yet. I need to go get some new feeler gauges when i have some free time this week. i am assuming i just adjust it following the tsrm?
