Without actually riding in cadfan's car, it's hard to say.
On the one vehicle I had this happen to me with (a v6), for all intents and purposes one cylinder was dead. The injector either wasn't firing at all, or it was so clogged that no fuel was getting through.
As you might imagine, on acceleration when lockup was engaged, this was EXTREMELY noticeable!1987 Ford LTD Crown Victoria 2-door Coupe - perpetually "sort of" for sale...

ever put a timing chain in it? if its the original 85 chain, its probably that crappy plastic toothed thing that gets real sloppy by 80k, or whatever that amounts to in fake miles.Originally posted by marquisman View Post86 Lincoln Town Car (Galactica).

UPDATE
I took the GM to the doctor today.... before opening his own shop 10 years ago he had 20 years in as a Ford dealer tech. He is known as Mr Ford in town! Anyway, the tv cable adjustment was right on, injector drop test fine, ignition scoped fine as well. There were 3 codes set.. I didn't get the codes but he said 1 was for idle speed control, one was for rich mixture, and the last was for EGR/ position sensor. When he opened the EGR valve at idle, it didn't affect the engine at all. He verified the diaphram was pulling the pintle and would hold vacumn well. He believes that the EGR passage is (partially) blocked.
I assume exhaust gas comes from a crossover in the lower intake, to a passage in the upper and then the spacer??? Friday he is going to clean the EGR passages and the idle air valve, then retest. Is the EGR sensor expensive if it still sets the code after? Again many thanks to all for your help!sigpic'86 GM LS sedan bone stock 113k triple dark sable, most of the bells and whistles, second owner.

you got the egr system right. Crossover in the lower intake, up through the center and out to the spacer.86 Lincoln Town Car (Galactica).

I THINK IT'S FIXED!
Took de Sade back to the Dr. today. The EGR passage in the spacer was all but completely plugged, as was part of the upper intake. After the roto rooter, and cleaning the IAC passages again, what a remarkable difference! Much smoother and more power throughout the whole rpm/speed range. Lesson learned? Don't ignore the EGR, and go hurt the "tech" that charged me to do the same thing 2 years ago (Mr. Ford said the spacer had never been off)

The right doctor is all it takes. The EGR does make a difference when its enabled. The passages really do need to operate properly. If its disabled, it will run OK but with the passages clogged up and the valve operating, the ECM leans out the fuel mix and advances the timing figuring there is exhaust gas involved. When its not there, it ends up running too lean and with too much timing.86 Lincoln Town Car (Galactica).
