Do you have a wideband?

no not yet but will be getting one the s300 is what showed the 16.x a/f

Without a wideband you cannot get an AF reading to tune by. You will need to take this to a tuner in order to fine tune any problems you are having.

You describe a part throttle issue, but your datalog is of the car not moving. To avoid damaging your engine since you do not have a wideband I strongly recommend taking the car to a tuner even if it just for a base map to run safely until your dyno appointment.

i had the same kind of problem..i had to change the throttle value into the negative like.. -2.75% to 100%.

i would say try this switch the tps and map sensor plugs. try that and run it again just to double check. cause it looks like most of the revs u made the tps is mostly at 0 %. and hops every once in a while. just my 2 cents. it wont hurt to try man. good luck

i had the same issue, crusin barley on the throttle i had a leaning out issue which causes jerkyness. i changed the injector lag time in the fuel trim parameter(or injector voltage compensation). set the specs for my injectors and it worked alot better. go to "injector-rehab.com" for the specs. it will also change your af ratios, so a wide band is highly recommended before you go to far.

Ive experienced this before with fouled spark plugs and one other time with a bad wire. Tuneup?
