Is this a bad idea?

[rdbee]

Last winter I noticed that my truck idled faster when I pulled the coolant temp sensor harness off. It was handy to warm up the truck or to boost the battery on the Clarke skidder we were logging with (3 cyl. 2 cycle Detroit).
Anyway is it a bad idea to put a switch on one of the wires to get an easy high idle setup.
Thanks

No need, just read this thread, step by step instruction are later in the posts. This is the proper way to get a fast idle.

I would not do an on/off, I have been thinking of putting a varisistor in or at least a set resistor. remember this affects od and torque lock. for just high idle i would follow mfgguru's post. the other way you can incrementally increase rpm's, but if you forget to set back, tranny damage in long run.
