Looking for control data

I have a 95 3.4l 5spd 4x4 It was a one owner truck before i got it. everything was serviced by toyota. I purchased the truck november 2017 with 190k. I now have 207k. Im looking for some baseline data to compare to.

 

What data do you need?

 

Kind of sounds like they're looking for recommended service for the mileage they're at now but the words control & baseline data throws me off.

 

As in scanner data. Live data. Rpm at various speeds. E.c.t. t.p.s% at idle..... Im just looking for something to compare to. Hard to troubleshoot when you dont know whats normal and what isnt. Not trying to waste my time and money being a parts changer. Any basic info and tips on pin pointing common problems would be awesome. Thanks in advance

 

Just what if anything has been done ??

What is broken how many codes have tripped and need addressed ??

Do you have the service records from Toyota ?? The service might have been oil changes and rotate the tires .

Does it still have the original timing belt ??

Get yourself the Factory Service Manual
