ptstill

Over the last 2 months my car has started missing on partial throttle. It only does now and again, so far I have changed the plugs, air filter and fuel filter. The engine is the carb version with auto gearbox. This problem makes it a dog to drive when u want to slightly up your speed, the engine is fine if you boot it. I've tried changing down when this problem happens but is still the same under partial throttle no matter what revs your doing. The problem is so bad the car does kangaroo hops down the road even at 70mph

Has anyone any ideas before I replace fuel pump and all ignition side.

The alt is also under-charging.

Regards.
