Hello all,

So since I bought my van back in November, it's had an issue where when I first start when the engine is cold, it putters out and dies. I'll then have to start it again, anywhere up to a maximum of four times if it's really cold outside. I haven't thought much of it and have marked it off as a nuisance while I fixed other problems, but now I have time and money to address the problem (hopefully).

Beyond this, after I've driven around for a while then park the van for a bit (for like an hour or so), when I come back to it and start it again it will start but seems a little weak and kind of putters. If I start to drive right away it will struggle a bit but eventually "come-to" and be back to normal. The same will happen if I sit and let it idle for a while until it stops the puttering.

So my question is, what do you all think this is? I think it's likely a vacuum leak, but am not sure. I would appreciate y'alls advice as you are true experts! Thanks!
