Unfortunately, my car has that damn hesitation. I know that the fix with the boost controller harness could possibly fix the problem. Has it worked for all of you that have done this mod? The catalytic converter is newer.
Do you think it's an exhaust issue. My buddy has an FD and had that same problem. He replaced the ground cable to his battery and didn't have the problem anymore???????????

 

OOPS I FORGOT! I have an 87 FC.

 

I read somewhere that the skip is due to inadequate ground. They suggested running a secondary ground wire from the battery to chassis and also add another one from the engine to chassis.

I am sure the thread on this will pop up if you do a search on the subject.

Yep, re-ground the engine to the fire wall, the ECU to the firewall, and the battery to the fender sidewall with at least 8 AWG wires.

It won't help if the 'puters or fuel injectors are bad, but it will solve the problem 75% of the time.
