When a 'check engine light' (MIL=Malfunction Indicator Lamp) is turned on, there is a DTC (Diagnostic Trouble Code) set/stored in the ECM/PCM (Engine Control Module/Powertrain Control Module). This code identifies which engine management system component/function experienced a malfunction. Once you pull/read this code, you may begin diagnosis. I think you'll find P1529 (MIL On request from the TCM - Transmission Control Module.

Your computer on your firebird is logging a trouble code when the check engine light comes on. Save yourself some money and go to a local parts store to use a scanner. Most parts stores will hook up to your car for free and tell you the codes that are being logged. You can spend a lot of money assuming what parts may be malfunctioning by just throwing parts at your car. Check it first and you will be money ahead.

I think you mean the engine stalls or cuts out at Idle/30/60 mph.
More info wanted,as first is it a Man/or Auto ,what engine have you got 6 or v8??? When last servised by who,How many miles on the clock,dose it smoke when driving or starting ,are the revs ok on idle ,,about what temp dose it run at the 30/60 mph etc etc???

run the fault codes to find the reported fault
engine lights report on engines and transmissions
could be actuator or vacuum to actuator, dirty transmission oil or pump pressure problems

well your tranny is slipping check your tranny fluid make sure its not low on fluid

Probably is a belt. Look under the hood while its doing this and see whats smoking. Look at the alternator,power steering, etc... You will be able to see the problem. If not, take it to someone who can put it on a computer while the chk engine light is on. Good luck

the turbo is the problem and needs replacement.  It's sadly expensive so try a junk yard or a turbo rebuilder.

As with any check engine light, the only way to find out what the issue is is to have the code read. The dealership can pull the code and let you know what the issue is.
Before considering driving the vehicle to the dealer though, check the obvious: oil level, coolant level, transmission oil level.
If your uneasy, have it towed.
