Suzuki Swift Sport 2018 1.4T Intermittent High Fuel Trims
Hello,
I've been trying to track down an issue with my car for a while now and the only issue I can spot using my OBD tool that sticks out is that sometimes at idle the car will climb to a +25 short term fuel trim that immediately falls to 0 under acceleration, HOWEVER today this behaviour does NOT happen. It will go as high as +5 STFT at idle. The idle does seem quite rough in general not majorly bad but it's more in driving there is a small hesitation when accelerating hard sometimes. Are there other values I should potentially look at to help resolve the issue?
I've been graphing OBD outputs on my car for months now so I have quite alot of data I can pick through.
