Thread: New noise..again..help?

Well I fixed the vacuum leak and it was fine. Now there's a new gurgling noise coming from the engine on idle. Any ideas?

Is it only when it is cold?

No don't think so. It went away today.
It was odd actually, it was making the noise when I drove it this morning. After class I filled up to half a tank and dumped a whole can of seafoam in, started driving. Few mins later it threw a system too lean code and started really acting up again. Then a little while later it when off and now its running great and my mpg seems way better.

Maybe it was a gremlin doing a post Halloween hit and run on Pontiacs
