bucking when hot

[Kaasler, Ingvar]

My 89 200TQ has begun to buck when the car is warmed up and under load, such
as taking off from a stop heading up hill. Cruising there is no problem.
This only happens when the car has warmed up. I've replaced the following
items: fuel injectors and inserts; distributor cap, rotor, wires; all vacuum
hoses; fuel filter, fuel pump, FP relay is OK; temp senders for ECU and Idle
circuit,

I would like install the check engine light to read any codes but am not
sure where to access terminal 31, and 33 on the ECU for it to blink out
codes. Scott Mockry's site is not specific as to where that lamp can be
hooked up to existing wiring.

 

Any suggestions or ideas?
