Misfire?

[drewesq]

My car kind of hiccups when pulling away at low revs - as if low on fuel. I have have changed the spark plugs and HT leads, fuel filter and air filter and squirted a little wd40 in the sensor connectors..

It is still doing it a little but nowhere near as bad. If I put my foot down it doesn't seem to happen, only really in 2nd and 3rd do I notice it at low revs say less than 2500rpms

Does anyone think this just may be incorrectly gapped spark plugs or something more serious?

Thanks
