Hi all,

2003 Lincoln Town Car with 81,500 miles.

- Ignition Coils replaced

- Spark plugs replaced

- Cleaned out throttle body

- Cleaned MAF

- Mechanic checked it out and said there weren't any vacuum leaks so I'm puzzled

- Tried Chevron Fuel cleaner and it didn't do the trick (figured)

The car's been hesitating after engine is warmed up & It only hesitates once when I first start driving it at low rpms 1K-2K RPMS or accelerating around 20MPH-35MPH. And strangely enough, it only does this turning right. It has never hesitated driving straight or turning left which is confusing but whatever. I've put roughly a few thousand miles as of this year and no codes pop up indicating a misfire. I ended up trying out Mode 6 on my Blue-driver scan tool and it says all tests pass except for TID #56. From the research I've done on Google, this failure indicates the potential misfire events or number of events required for a 1000 rev test (rev no. varies). It just says fail on my scan tool. I'm not sure what this means and how I can diagnose this as the other data in Mode 6 is telling me there aren't any misfires happening on any cylinders.

On another note, the live data is telling me one of my heated oxygen sensor is running lean (Xtool D7), could this also be a cause to the misfire? I don't see the short/long term fuel trim surpass the maximum allowed threshold (-10% to +10%)

Any help would be appreciated and If I wasn't clear on a particular portion, I could try to add on more detail.

Best regards,

Lofi
