P1341: Multiple cylinder Misfire with Fuel Cut-Off Ok guys, here's the situation. I was having the white/bluish smoke issue at startup and the howling sound/vacuum that stoppd when dipstick was removed. I was also getting the intermittent SES light and rough idling.I had the OSV/rear manifold gasket cover changed and the smoking immediately stopped. I also cleaned the MAF and the SES remained with rough idle for about 300 miles. Then the rough idling stopped and SES stopped on its own. Now, 100 miles later the SES is back and the idling is rough, but not as rogh as at first. I went o AutoZone and got these codes and printout P1341: Multiple cylinder Misfire with Fuel Cut-Off Ok guys, here's the situation.
