Coolant Temp Sensor Q
Posted 03 February 2004 - 06:20 PM
Cranks over, spark is good, (plus new cap and rotor) -finally after 20 min it started, but runs very rough now. Check engine light on intermittant; fault code 21- which I believe is coolant temp sensor.
Anyone seen a bad temp sensor cause rough idle like this?

i've had the code come up from a sloppy wiring repair i did, improving the repair fixed the code. it could be the sensor itself as well of course.

I just went ahead and replaced the sensor ($17) and cleaned up the engine harness connector as best I could.
Runs great now
