I've changed my spark plugs and wires myself. It was a tough task trying to remove the by pass water hose. Probably because i don't have the right tools. Any have any tricks? My car idles rough now because I accidentally took out the Throttle Position Sensor while removing the throttle body. It idles fine if my headlights or my AC is turned on. Otherwise, the car idles under 750rpm and shakes badly. Any thoughts anyone on this?
I did put in the bosch platinum plugs and new OEM spark plug wires and cleaned the throttle body a little bit. I also noticed a screeching sound for about 10 minutes but then it stopped and never heard it again.
thanks,

Did you reset the ecu as well? That may/may not help... I always pull out the efi fuse when i do a tune. The Throttle position sensor should have a white mark that shows its original position. If it doesnt, then adjust it manually, undo it, adjust it and tighten the screws back up.

PS. I have the turbo engine, so this may not apply to the SC300.
