I just did a bunch of work on the manifolds, now the car runs fine until it warms up, then it surges and if I don't keep my foot on the throttle it dies. It will bounce to almost dead when I parked it at home and when its about to die it makes a whoosh kinda noise and I think the acv is clicking, other than that I don't know where to go from here.

 

more info on the car would help.

 

Okay, well I pushed on the AFM, BAC, and TPS connectors and now it seems to work alright.

It's an 87 GXL sorry. I'm gonna keep an eye on it and reset the TPS tomorrow cause I messed with it.

 

Well if it works fine after pushing in the connectors you should be fine, just loose most likely. However if it still does it, you may have a vacuum leak (you said you worked on the manifolds so I assume intake and not exhaust lol)

 

My idle is relatively solid at 900, I adjusted the TPS as per the FSM. However when I go to adjust the set screw on the top off the TB I put the jumper in and the engine dies. Anyone have a solution/ reasoning for this?

I'm gonna go clean my BAC at the moment, I already cleaned the ACV and replaced the gasket/ check valve.


Update, I cleaned the BAC and dressed the gasket then was able to put the initial set jumper on and adjust the screw. My BAC read 12.3 ohms which is the top of the limit, is that any indication on it's remaining useful life?
