Alfa Romeo Repair: Alfa 156 Selespeed injection failure warning light, alfa 156 selespeed, octane gas

Question
Hi there. I ahve taken delivery (ex Singapore) of a 156 to handle for an exporter. I ahve had heaps of problems with it, and now that everything is runnig ok, I put some 91 octane gas in her , drovbe her 5 miles to home and she will not start. The injection failure light is on. Having looked at the manual, I see I need 95 octane.
Can htis be cured simply. Other issues were srs light, brakes, shocks, bushes.

Thanks for your help.

Answer
Sounds like a vehicle that was driven hard and put away wet.
Would need miles and age to point you in a direction.  Try cleaning up the grounds for starters.  By the way, the problem was not caused by the low octane fuel, all that does is reduce power because with the ping the computer will retard the timing.
