K, I've got the car back together, and its still really idling like shit, im gonna put a BRAND NEW IACV and TPS on it tomorrow (no more used shit, b/c I'm still getting those codes 7 and 14), but just incase that isnt my problem, does anyone have a vacuum diagram for a 90-91 LS?

what is it you want to know?

The only vacuum lines you need is the fpr and brake booster

 

I dont think so blake, cause there are 2 nipples on the back of the intake manifold that will stall the car out when covered up and stuff, I need more than 2 vac. lines... lol

What are you talking about? u have vac lines for:
Evap purge
Fuel pressure regulator
Map Sensor
PCV
Brake Booster


Evap purge is emmisions shit, pcv is emissions shit. So that leaves map, brake booster, and fpr.

 

Then maybe my map sensor is bad, i dunno why it would stall out when I put the top 2 right vacuum lines on.. Somethin else must be wrong then..
