Can anyone put some though to an issue that has developed in this warmer weather (may be a coincidence and not related at all) My Bj8 has started missing above 3500 revs under hard acceleration also with an occasional backfire in the exhaust. The car will drive perfectly up to these revs even under heavy load in top climbing a steep gradient it will not miss at all. As soon as I slip out of overdrive and give it some beans it feels as if it is being held back and sometimes wakes the dead with that backfire.
The coil is fairly new with petrinox ignition, running on twin SU carbs with a tubular manifold and side exhaust. The valve clearances are ok and the plugs seem to be burning the correct colour if a little on the lean side.
