Hi all, recently my x14xe started misfiring, it is only when I put my foot down when pulling away, (doesnt happen if I pull away gently) and it only happens under 2000rpm, once I'm above 2000rpm (foot to the floor or not) it fires on all cylinders absolutely perfectly. I dont understand it could this be a fueling issue? I cant check for engine management light, as its always on because I cant use my secondary air pump because im using a pro tec manifold. The plugs and leads were brand new on the engine back in october after it had a full rebuild.

check the wire's on the aif flow sensor, or it could be ur map sensor, it confuses the tps reading to the ecu and you get a slight misfire but only when under hard accerloration, my gsi was doing the very same thing

could a leak on the hose to the map sensor cause a misfire?

It will no doubt mis fire when you accellerate gently too.

Still doing this and its annoying the shite out of me, tried new HT leads and it made no difference as did cleaning up the plugs. Checked all vacuum hoses, no leaks, any other ideas?
