My 1990 900 SPG has an intermittent rough idle problem. The car seems to run great except for the fact that at a stop the idle fluctuates between 700 and 1400 rpm as if the computer is constantly over and then under compensating. When idling properly, it purrs at a steady 1000 rpm. This problem only seems to occur after driving the car for a bit on the freeway. I have had several vaccum hoses replaced and tightened and my mechanic says that his only recourse is to start an expensive diagnosis of my computer. Any thoughts? Thanks jsweetnopsamneering.ucsb.edu
