car revs high on start up after fuel filter change out
So before I changed my fuel filter the car would start hard since it was clearly starving for fuel. Now when I start it up it fires up nice and quick but it gives itself a little high rev on start up. The cars seems to be running good down the road but I want to get all I can out of it.
With that being said is it possible that the cars computer has compensated for the fact it was starving for fuel before by running rich? If so is there anything else I should do to reset the computer besides just unplugging the battery for a few minutes? Or am I completely insane?

The way I've found to reset the IAC is to unplug the IAC valve, unplug the MAF and unplug the TPS. Start it up for a few seconds. Then shut it off and reconnect them all. This worked for my engine/PCM a couple times years ago when I was getting weird fluctuations at start up on my 427ci.
