You want it fully hot.
Let it get up to operating temp. This might have been why the readings were lower.... Also, you can pull your EFI fuse instead of disconnecting your crank sensor. Either will do. You will have to pull the fuse regardless to clear the codes [or use a scanner]. Easier to acess than the sensor connector too. I do the crank sensor out of habit. Alot of newer cars have throttle by wire, so you need the ECU powered to open the butterfly valve. --------------------  |
