Pull up resistor question

Hey all,

 

Just wondering if it would be safe to use a 1/8 watt 1k resistor as opposed to a 1/4 watt as a pullup from my distributor on my l28et. I have a 1/8 watt handy, if not I'll be heading to the store tomorrow. Just curious. I found this suggestion on diyautotune.com

The reason a 1/4 watt is recommended is because a 1k resistor with 14 volts applied will flow .014 amps, which is equal to .196 Watts or about 1.5x what an 1/8 watt is designed to handle.  

 

The 1/8 watt will certainly work short term, but keep in mind that you will be overheating it.  Personally, I would swap it out just to prevent any issues in the future.
