Hey all I've posted a couple times about this already but I'm hoping I can get more responses. I have the above codes, have had them for a week or so. Car intermittently stalls at red lights, rough idle. Today the check engine light started to flash as soon as I got home. I started it back up and the light stayed on, but I have to bring it somewhere tomorrow to get looked at. I was thinking the crankshaft position sensor or o2 sensor to start. I have changed the spark plugs 2x as well as the ESIM valve, oil and filter change, ran additives all to no avail. There is also a drip coming out of the exhaust at the connection to the muffler would this be the cause? Sorry for the essay you guys are very informative and I hope to gain more insight on the issue. Thanks all
