1985 oldsmobile calais 3.0 6 cyl. 156000 will start and idle no problem but when i go for a drive it will loose ALL power and stall. check engine light is on and i did diagnostic test that said egr failure but i took it off and it works fine then i played with the idle air control and it helped it idle much better so i bought a new iac but the problem still occurs. could there be a vacuum leak and if so how and where willl i find it. also a black hosing that plugs into the o2 sensor and the egr was not sucking air until i cheated a bit and connected it to another hose and now there is suction. PLEASE HELP, DESPERATE FOR ANY INFO. spark plugs were just changed. also how likely it to be the fuel injectors????
