Hello. I have a 93 volvo 940, for some reason my idle is fluxuating up and down. It comes close to quiting at times. Any ideas what this could be?

Been chasing similar problems. Possible vacuum leaks, idle air control valve, fuel pressure regulator. Check error codes for IAC codes 223 and 233. I sprayed starter fluid around vacuum lines and intake and discovered massive leaks in intake manifold gasket.
