Default Random Cylinder Miss at idle/low rpm
I've had this problem since I built the car. I've got a 91 LX with an 86 TC engine and Turbo (T3). Rebuilt the engine, TURBO IS ORIGINAL. Iridium Plugs, MSD Wires, Cap/Rotor, Mallory ign. Module and good fuel pressure. Running 87 computer/injectors/electronics/VAM. Custom intake, NO INTERCOOLER. Problem occurs cold/hot all the time. Frequency of occurance is about one miss every 7-10 seconds. Timing is correct. I've heard this could be due to a turbo/wastegate issue.
The miss is a confirmed random miss (scoped). Any ideas?

You know with a turbo or supercharger you should run 93 octane?
