stalling

[glc530]

I have a 92 with 102,000 miles. It has had an intermittant stalling problem when I come to a stop and the rpms drop below 1000. I need to rev the engine to keep it from stalling. I had the MAF filter cleaned and it didn't stall for several months. Then, the throttle body and IAC were cleaned. A connection for a small hose had also come off, so the mechanic epoxied it back on in order to save me a couple hundred in replacing the entire part. After a month, the engine is stalling again. They said there are no vacuum leaks. Any ideas? Thanks

By the way, I'm currently car shopping, so if anyone is interested in adding to their collection. The car is teal with gray interior and touring package. I have all the records including the Port documents. glc530@juno.com
