Over the past several months I have been noticing that my engine "revs" as I try to stop.the problem is intermitent but seems to be occurring more often. I had the dealer check it out-the 1st time I believe they just did a test drive and said they could find nothing wrong. About 1 1/2 months later it happened again and I bumped into a security gate at work. As I approached the closed gate I had my foot on the brake as I "eased" up to the card reader to open the gate, all of a sudden the engine started to rev and car inched forward as I tried to apply more brake effort. After a few seconds the idle returned to normal. I took the car back to the dealer 2 days later and paid for a computer diagnostic-again nothing was found and I was told it could be almost anything, and they had no suggestions on what to do. They told me they could replace "random" parts but it would cost alot of money to do so. I am not positive but this happened to me at least 4 times. The car revs for a few seconds as I brake to stop and then returns to normal idle.
