from a cold start in the morning the last two days my van has thrown the CEL on start up. the first time it happened it had a really low idle and i shut off the van after a few seconds. It wouldnt start about a minute later, not even cranking, lights on dash illuminating normally. i didnt do anything to the van and then it started up after waiting a few minutes. The CEL stayed off the rest of the day when driving it. There wasnt any stored codes when i checked that night. The next morning on another cold start the CEL came on again and turned off after about 5 seconds. It also idled really low for those few seconds and then picked up. As far as i can tell the van drives the same, same power and acceleration. However there is an increased exhaust smell while driving, not raw unburned fuel smell just exhaust. It also sounds different than it usually does. Does anyone have any suggestions on what components i should look at? The thing that confuses me is that there arent any stored codes so idk really where to start looking.
