the 88 that i'm taking the bad eninge out of has that. have not looked at the 87 to see if it does yet. and also why would you need to swap the injectors?

Mid 87 and earlier cars have low impedence injectors. Newer cars have high impedence injectors.
Cars with low impedence injectors have the item shown in my jpg. It's called a Solenoid resistor. There is a resistor in it for each of your injectors. It's not a high tech device.
A true 88 car would not have this device.
Ohming out an injector is easy. One meter lead on one pin of the injector......the other lead on the other pin on the injector. Put the meter on ohms. Read the meter. On a low impedence injector you will read approx 2.2 to 2.5ohms.
The ECU is looking for approx 10ohms resistance from the injectors whether its a 87 or 88. The 87 and earlier did this with the solenoid resistor. The later cars do it with the impedence built in the injector. You will eventually destroy the ECU if the resistance is not there.
I doubt you have a real problem. Start changing the engine now. The injector issue can be dealt with later. It's not a biggie in the scheme of things.
