The car is a 1998 Oldsmobile Intrigue with 3.8L V6 engine (3800 Series).  I've been doing my research and due diligence, but please understand I'm very inexperienced with automobiles.

I went to Autozone and the reading I got from the OBD II tool was a P0171 error code.  A lean or rich condition on Bank 1.  First, I don't know where Bank 1 is.  I have a feeling it's a cracked intake-manifold, an intake-manifold gasket leak, or both.  But let's assume I have no clue where the vacuum leak is coming from.  And I don't want to use a carb cleaner -- I read that I could cause a fire and I don't think I'm experienced enough to use something like that.   I'd prefer to err on the side of caution.

I've seen on youtube a long-time mechanic who uses a cigar as a cheap alternative to a smoke test machine.  But I'm not sure if something like that could be used if you have no idea where the leak is coming from.

So I ask those who are far, far more experienced than me.  What ares some methods I can use if I have a vacuum leak, but I literally don't have a clue where it could be?

Thank you.


Question: Facebook - Music, Books, Interests.. are they all included in "Likes"?
Answer: The facebook Likes api for the graph includes: likes, share counts, comments and notes. You can make one call to retrieve all likes, but it is not just limited to likes, they could have put a comment on the page describing that they didn't like it, and it will still show up here.
