Hi all
I've been lurking here for a while after picking up my 07 NHB FN2 GT
I'm looking for some advice
In the morning when the car is first started the engine has an occasional misfire / stutter as the throttle is applied. it does it every 10 seconds or so regardless of throttle position or engine load (obviously very low as the engine is cold)
I've had something similar on a previous fiesta ST that had a faulty spark plug so I'm trying to see if this is just normal for the K20
The spark plugs are 2k miles old from Honda

any advice etc would be very much appreciated.
Thanks
Lewis

Feels like a kangaroo, quite common I believe, mine did it, on cold mornings I would start it then put my belt on etc etc just to give it a few secs before pulling off

Sounds like mine, mine feels lumpy / rough for the first few minutes. Sometimes it can be really bad and quite hard to drive without kangarooing down the road. You do get used to it though!

Same with mine, but have found shell v power nitro makes a big difference, not eliminated it but much better. Try a tank full and see if it helps.

Its the ignition retard based on the coolant temp table.


Perfectly normal
