Hey I'm new to the site and I recently purchased a 85 Camaro with a carbed 84 z28 305 engine in it and really dont know anything about the car other than when i drive it, it runs and sounds fine but once i hit 45 mph the car starts to stall out... which sometimes it does stall out.. any thoughts? The car has an auto start/alarm system that the prior owner thought it might be the issue. Also he purchased it with the auto start already in it. So I don't know...
