Default TTS Datamaster scan

Hello All

Wondering if anyone can have a look at my scan results and see if anything odd is showing up. New to this and cant read the printouts properly yet

86 L98 Stock 70,000 miles
New BoschIII injectors from FIC (3WEEKS AGO)
Fuel pressure is good and holding (measured after injector install at the garage)
New coolant temp sensor--front of intake
New Cold start sensor--front of intake
Cleaned TB
Cleaned MAF

Was very hard starting cold -much better with new injectors and sensors
cranks for 2 secs in the morning and fires right up
starts very well all day long

The major issue i am having which prompted me to scan the engine is in the AM after starting--hesitates and bogs down when you give it any kind of pedal-just like the old choke/ carb days--until about 10 mins into the run when fully warm---runs great then except for a slight rumble at idle--nothing too serious.

Idle is a little more rough when cold--not to the point yet where it wants to stall--but it is noticeable.

I thought i would look into figuring out this scanning stuff but its a little complicted for me right now.

If someone is so inclined to have a look at this file and let me know what you think--that would be great

Thanks in advance

Can't help with the data, but wondering how you saved that as an excel file? I have a datalog session for mine and can't figure out how to send it as an attachment in datamaster form or any other.

You have to save it as a "CSV' file through Datamaster.

CSV is opened and viewed with Excel--Once opened in Excel you can "save as" a regular Excel file or 1 of many other file format options.

If you have any insight on my scan or the engine issues--- i would appreciate it

Thanks
