Starts, Idles, wont drive?
 

Hello. I was looking to buy a new fc.
i wanna know if anyone knows the solution to this problem.
1987 Rx7 sport.
the owner claims to have done.
-"full system flush"
-fan shroud
-odo cable
-head and tailights
-new waterpump
-thermostat
-power steering pump
-new plug wires
-spark plugs
-and an air filter
(some of these may not be important to the situation, adding them just in case)

Ive seen the car run. And idle. But he said that he cant get it to move forward. It dies in the attempt.( I may be stupid but i didnt see a thread about this) He claims it should just need a new maf. But Im a little skeptical.
