Noticed on my 30 minutes commute home a little hesitation as accelerated and idle hovering slightly, but as got nearer home it got worse where it was almost stalling at idle.
Took a video below and when I stop feathering the accelerator it gets really bad with black smoke coming out the exhaust and around the engine.
Fault code reads 5 long, 5 short so all ok there.
An hour later I tried the engine again and the same problem occurred. Tried it again 1 min later and all ok ish.
I thought I'd check the following;
Spark plugs and spark,
I'd there anything I should consider?
