Yes it will be fused. I remember a problem with that carb. (a long time ago,
sorry) It has an inrichment type choke if I remember right. It likes to
stick. What was the readings on the failed test...Hi CO? Can you post all
the readings and what the limits to pass are? Who tested the ECM? you? Are
you at your shop working on it? If so the Ford book will have a section on
what to test if you get no output from the ECM. Good luck with that thing. I
used to work on those cop cars all the time, I dont miss that system. :)
Never could figure out why Ford put the carb on those, all the 305's had EFI
by then. Maybe they needed to "use them up" ?
No, first the owner connected a scan tool to the pigtail under the hood and
"no-codes" . Later the owner took the car into a shop that specializes in
"failed emission vehicles"and the shop stated the same thing "no codes", yes
the vehicle does emit high HC's but runs fine. Is it maybe a unique problem
with the 91 interceptors.
