I have a 1990 CRX DX (B17 Turbo) and I was driving the other day and the car started to idle very low and when I come to a dead stop, sometimes it just shuts off. I parked it at home and the next day it was running fine...then later on in the day I was driving and the car died. I started the car up and revved it up to 6K to keep it from dying but it still dies out.

So I bought some engine starting fluid and had a friend start it up while i sprayed in the stuff into the throttle body. The engine stayed on as long as I sprayed. When I stopped spraying, the engine dies out.

I have a vacuum gauge and the vacuum is lower than normal so I checked around for vacuum leaks but can't find any leaks.

I have 450 DSM Injectors, V-AFC, Walbro 255 fuel pump. Car was dyno tuned too...

What could the problem be? A sensor? Or a fuel problem? (Locked/bad injectors?)

 

Any codes ?

Almost sounds like the iacv located on the back of the mani. If you ever leave it unplugged, the same thing you describe will happen

 

Ok, noticed the plug for the IACV was unplugged. Plugged it back in but the same problem...it won't start up.

Well if it was unplugged then the car was throwing a code, did you reset the ecu ?

 

ecu resetted...same problem

 

there might be a hole in your vacuum hose or you need bigger fuel injectors

Look for this or hooked up incorrect. Check valves or missing link?
