D110 missing?/hesitating

[polardoc]

1993 NAS Defender;has a jerkiness/missing always between 2600 and 3000 rpm.Never there at lower revs,disappears as the revs drop or increase.In all gears,hot or cold.

Distributor cap and rotor is relatively new and looks good, plugs and plug wires are new. Fuel filter is 1year old. Coil is 10 years old. ignition module is 11 years old.Everything else original.

Any ideas/help please!!

Check your catalitic converter (does it rattle?), are the fuel injectors clogged? Run some Tecron fuel injector cleaner through it.

same problem

but I noticed that it only happens with some additional electrical load...ie if I have my headlights on or the AC blowing...

Can anyone help?

In your case it's likely the alternator not putting out enough and the system voltage is dropping. I just read and answer your non start post. Add to what I said there get the alternator checked.

if it was a power supply issue, alternator not keeping up with the load, would i see the battery gauge drop during the time of hesitation?

Note, that my other post is actually regarding another 110 that I am babysitting that just happened to "die" on me.
