Cold Start Misfire (on choke) APU

[Leon Mike]

Any ideas what may be the cause...I know it could be a long list of things but is this a common problem?

When the engine is stone cold it would intermitantly start to misfire quite badly for a good 20 seconds.

Never seemed to have an issue when warm...always seems to be when on choke.

I have tried changing the choke/temp switch just cos i had a new one lying around.

It's not a real issue...it just sounds dog rough

A misfire is hard one to track, without more detail or engine mileage etc - sounds like it could be maf related! or your injectors need a good flush out, or a spark plug / coil pack on a the way out! probally dosen't help you much, but i'd start with these things first! or just take it to seat and see what they say!

ah yes....new maf about 2000 miles ago...new plugs at the same time Millage is 107,000 injectors are a possibility tho.
