It actually shows too lean there on the log.
Also attach the tune file...

You have an issue with extreme noise in your TPS signal.  The erratic TPS delta is causing erratic amounts of accel fuel to be dumped in constantly.

It could be a wiring issue, sensor issue, or mechanical issue such as no free play in the cable.  

TPS delta would usually be less than about 0.5%/100ms when steady state, yours is touching ~20%.

thank you for the reply's!! i could unplug it for a test?

[Adamw]

Im not sure how unplugging will really give you anything useful, obviously the noise will disappear when there is no signal.

@Adamw you are a STAR! i did a bit of reading from your post, i saw there is a deadband setting, i set this to 18%, as a test... no more cold start issues, AFR is on target , and it runs far , far better, so, going to fit new tps, with shielded cable, new connectors too!  again THANK YOU!!
