Judder/misfire
Hi,
Had my car maped in the summer with a unichip, FMIC, 550cc inj, walbro FP...and i was very pleased.
Now the cold days are starting to creap in my getting lots of what i think are missfires on acceleration, almost to the point were i can't touch the peddel with out a pop or bang and a missfire.
Talked to the chap who mapped it and he says that he does not think its the cold weather but could be a temp sensor problem.
What do you think?

don't think it will be the cold weather to be honest, usually the car would feel slightly more responsive. Have you checked the plugs // coils. What year is the car? have you tried an ecu diagnostics check to see if it flashed any error codes up?
