my 1985 jaguar xj6 idles fine but cuts in and out during acceleration. Cruising I hardly feel it.?

Question

Update:

My spark plugs are clean and so is the distributor cap. The engine has 2 thousand miles on it. Where should I look?

Answer 1

Faulty carburation. Clean the carbs and make sure they are supplying extra fuel on acceleration. Sounds like clogged jets or an enrichment device not working.

Answer 2

That's nice. Did you want to ask a question while you're here?

Answer 3

Have the fuel pump pressure tested.
