1990 GX N/A
Emmissions removed. BAC intact minus coolant lines.


so my rebuild had been running weird lately. I found a vacuum leak on top of the housings which I determined to be the old injector grommets.

anyhoo, I got the new grommets in today. got home from work. took off the throttles body and dynamic chamber as a piece, and then the upper and lower intake mans.

I installed the new grommets, and removed the 6pi sleeves while I was down there since im not using the system anyways...

anyways, long story short. I get it all back together and go to start it. I start it in gear to eliminate the AWS... oddly it revvs very quickly up to 3500 rpm. weird. I unplugged the bac and it didnt go as high but still revved quickly on startup.

bascially, it wont stay goin below like 2 grand, ive got to hold hold the pedal down fairly heavy. it seems to be running a bit rougher and the exhaust is popping a lot.

it may just be because I have the hood open, but its making a big swooshing sound. could this be due to a new giant vacuum leak somewhere?

help me out guys :P

 

as an update.... above 1800 or 1900 rpm it runs but very roughly. it is backfiring and spitting a lot.
I cant get it to hold below 1800 it just falls off and dies...


help guys

 

Sounds like a vacuum leak to me.
