SOURCE: saab 9-3 engine into 9-5

the engines are different model engines since they run off the computer im thinking that you need to set the computer to the 9.3 since the specs run the 9-5 at different frequency the enigine modules still think its a 9-5 in which you want the computer to run it at 9-3 this gives the high throttle reving

you need a laptop and your cars software to set the idle control for vehicle and possibily the proper idle control module for engine

It might be the water temperature sensor for the brain not reading the right temperature, causes wrong parametres in the warming up periode, and then the diagnostic lamp will show.

Hello. I had the same problem when the Check Gearbox light came on, it would be very sluggish. It turned out to be a small sensor in the transmission that lets the car know what gear it is in. It started to go out slowly and only sometimes would send the information.

Hello
Could be nothing more then dirt and corrosion on the battery cable ends.

Look at the cable ends where they connect to the battery if there dirty or corroded you will need to clean them off with a wire brush.

Another possibility is the starter has a dead spot and will need to be replaced.
