No end of challenging problems between you and Steve Cotsford and his
Bluestar!  The list would be boring without you.

Is this the one you've replaced the distributor on? Revisit that first,
wires second, injectors third. Stumbling under load is usually a spark or
fuel problem.  I just had a similar problem and the coil secondary wire was
badly corroded at the coil.  Clean and spray them all with a little WD-40.

Rough engine - the latest pita I'm having to deal with on a string of many!!
I'm on a roll!!

Ok - hot or cold - engine starts and idles well.

Conditions - ISV disconnected due to Idle issues
O2 Sensor Disconnected to put ECU in default mode.

Cold engine: starts easily, idles easily, but upon attempted acceleration it
bucks, kicks, snorts, hiccups, coughs - finally smoothing out at speed.

Warm engine: starts easily, idles easily, but upon attempted acceleration it
bucks, kicks, snorts, hiccups, coughs - finally smoothing out at speed.
Only the bucking isn't quite so bad. Occurs mostly on the initial
acceleration after idling successful.

Suspicion: Throttle body switches out of limits and need adjusting.

Anyone have any ideas about this?

Thanks,

John
