Hello.

There is a saab 9000 M92 MT B202T and GT25. The auto was bought in stock and among other problems in it constantly drops the engine speed, sometime to a complete stop. ECU LH\Jetronic 2.4 with MAFF was replaced by Trionic 5.5. The problem still exists... Replaced all sensors and idle speed controller - the problem still exists... Now the very last idea I can imaginate that the speed signal to Trionic is incorrect or failed.

Other ideas ended... Burn not to offer))

Any suggestions? Txs.
