I have a 1991 twin turbo Stealth. When the temperature warms during the day, it runs fine, but if it sits 2 days without running it, it will crank in the morning, but goes dead a few miles down the road. The check engine light comes on. When I try to restart, the turbo boost guage pegs out, and I hear on the driver's side by the muffler a motor that runs. Could this not be releasing the exhaust? Do you have any suggestions to fix my problem? Do you have a suggestion for a good repair manual for this Stealth?Thanks!

 

Try reading the codes. codes and how to read them

 

You cannot use the "Key sequence" to pull codes off of the first generation (91-93) Stealths. Use this procedure.Pulling codes The active exhaust does not totally choke off the exhaust. Under normal cruising it lets the exhaust out the duals, if activated it only lets exhaust out the drivers side. It should not cut it off completely. 3SX performace carries repair manuals. I highly recommend getting a repair manual.
