here's a wierd one that just developed.
I recently changed my TPS, and adjustment was done.
the 93ls was alwasy the 'normal ls' that it used to be, however lately, about half of the time when i am taking off from a stop the car seems to have extra amount of power/acceleration . but then the power goes away after 5 mins. I have noticed though, that the extra power seems to be there when the engine is running colder in the morning, that is hasn't reached normal operating temp.
could someone care to explain this, and also, how can i keep the 'more power' mode going even after the car has reached normal temp ?

could be your IACV or idle air control valve, or your throttlebody is dirty,
the IACV is en expensive part about 600 bucks, manual says replace if thats the problem but you can clean it with TB cleaner, just a lot of patience cleaning it hopes this helps
