Hesitancy / Misfire 1500rpm-2k COLD only
« on: October 05, 2021, 09:16:56 pm »
Hi Guys!

As per title.
Fairly stock G40 which when cold, first 2miles or so, produces a real hesitancy around 1500-2k.
Idle is fine hot or cold.
Higher rpm's seem to sort it - like it's forcing the engine to fix itself.
Warm engine sorts it too.

This leads me to thinking it would be the blue temp sender as that is temp dependant, but it isn't.

To my knowledge spark side is ok: Coil - Cap - Arm - Leads - Plugs

Any help much appreciated.

I have read these two threads which seem similar:
