Engine Miss
2000 1800cc J2 Lantra. Under load occasionally the engine feels its running
on 2 or 3 cylinders. One revs > 1500 rpm no problem. Gentle acceleration no
problem. If it were a carby I,d say the fuel pump on carby was defunct but
on fuel injection?
Newish spark plug leads, new ignition coil a month or so back.
Any one point me in right direction?
Many thanks
John

Sounds like a classic secondary ignition issue. Recheck your spark
plugs, wires, and coil. If your check engine lamp is coming on, check
the codes. If the ECM recognizes the misfire, it'll tell you which
cylinder is misfiring. If you don't find anything with a routine
inspection, you can swap the spark plug in question with that in
another cylinder to see if the misfire follows the plug.

Probably not a fuel delivery issue. That would tend to be most
prominent at high rpms.
