Connector is fine, replaced TPS several months ago, do not remember the brand.

1. Replaced the throttle position sensor and still receiving the TPS code

2. Car hesitates on acceleration from standstill until it warms up to operating temperature

Are theses 2 issues related?

It's the fan relay, 2/11 on wiring diagram.

When I wiggle/move engine cooling relay fan, the engine stops running.

I have the wiring diagram for the engine cooling fan and relay.

Can somebody explain how that occurs?

Thanks

I am curious/impressed as how you learned to do all this.

I am trying to figure out how the OBD2 reader is made from your post.
