apparently the guy whom im trying to buy this car from says it needs a distributor and a ecu. he says the car wont rev past 4000rpm.
i havent gone to see the car yet im going this weekend and would like to have the problem semi figured out or at least an area to go to before i go up on sunday. i already have another ecu and distributor for that engine. anyone have any suggestions?

 

There's too many variables to narrow it down to just an ECU or Dizzy. Do you know if it has any CEL's? Could just be a sensor. Need a little more info...
