1999 Alero dying

Hi guys. I hope you can help. Been a member here but have not really had many problems with this car til now. It has decided to start dying when i slow or come to a stop. It runs fine other wise but once i let go of the gas and start to slow to turn, it dies. Since then, the trac off light came on after it died and is staying on. It usually does it after the car is warm, not cold. Anyone have any ideas on this? Thanks

is there any overheating? when was the last time you got a tune-up, or got your fluids flushed out?

check ALL of your fluids and fuses. Get the cheap and easy out of the way, just to statrt the process of elimination. If these cheap fixes do not solve the problem, go to a parts store to get it scanned, and they can tell you exactly what parts to deal with.
