I'm Awesome
First, a quick description of my problem: sometimes (not always but often) my Tahoe would have difficulty starting the engine - it cranks fine but would take several seconds before actually firing up and when it does, it starts firing kinda sluggish. Once it starts, it idles, runs and drives nice and smooth.
(when the engine is cold, it always starts immediately, just touch the ignition key and she purrs)
This summer, I had the starter replaced - with the old (original) starter, I occasionally had trouble starting in all conditions. With the new starter, it was much better, but the occasional hot start problem persists.
Note: the new starter is POWER SELECT 6449N, the cheapest one I found on Rockauto.com:

I still have the old starter and only later did I notice that it has the heat shield on - either the mechanic forgot to transfer the heat shield or the new starter didn't accept it.
Now the question(s):
- could there still be an issue with the starter?
- after researching the hard hot start issue (also on this forum and FB group), temperature sensor was mentioned - now the question is:
- which one of the sensors is it, the one on top of engine, or the one on the driver's side of the engine near the plugs?
- how to test the sensor - will a OBDII scanner (I heve a cheap one) show anything funny with the sensor that may cause starting problems?
