Thanks for the response. It happens when hot or cold...no obvious difference in the symptoms when cold vs hot.
Wires were changed about 6 years back, look fine now, and sparks looked good too but they are getting old so I'll replace those and see. I looked in the distributor cap (it's new as of the last 6-10 years) today and it seemed really clean in there but didn't dig deeper.
I should specify it is only rarely a' violent' bucking, and is often just an erratic choking that can come in little quick sub-second spirts up to longer hesitations of a few seconds.
I'll get my hands on a diagnostic and check 12s. Thanks.
