Poor performance at 85 mph on my 88 C4
Does anyone know if the factory installed a speed control or RPM
limiter on 88 C$'s. Mine runs very rough, and seems to be misfiring at 85+. Any suggestions for resolving?

The long shots: Knock sensor is signaling the Electronic Spark Control to retard the spark. Does it feel like it's leaning out? Fuel pressure slump? As these cars age, we hit 'strange' problems like primary ignition wiring faults and failure to pull enough ignition current. I'd not expect that to show up at 85 but it might be worth a look if everything else checks out. -- PJ '89 auto coupe, '02 6-spd coupe
