i was watching shadetree mechanic today, and they brought up a point when changing the coolant temperature sensor. Since the sensor tells the computer if your engine is cold and when its cold it dumps more fuel, then if it was bad it would run rich 24/7. My car does, it constantly runs rich and gets crappy gas mileage...could this be a reason for the problem?

" I'd rather run last in a full out race, than to NOT run at all ".

 

When mine went bad my exhaust smelt like rotton eggs both times and flooded out my engine with fuel. taked 15 mins to change very easy also change the conector i realsied the connector that was on it even tho it loked good didt have good contct with it.

 

I noticed that my grand-am(94 3.1L) exhaust smelled like rotton eggs this morning could the coolant temp sensor be bad in it?

 

are you getting any codes. Mine when it was bad it would smell like rotton eggs for a 3 hr drive id come home and itd still smell like it. Give it a shot its only like a 3 dollar part

 

14 bucks actually... only go with ac-delco stuff. Hey RS, did yours throw a code? mines not...

Is it the temp sensor in the driver side cylinder head?

the CTS is in the front of the intake manifold right next to the thermostat. it's around $12. when mine was bad it didn't throw a code either. those sensors can be lil bastards sometimes.

It's that thing?
Try this
Take it out
Go to bench grinder with wire brush on it.
Polish it clean.
Reinstall with pipe thread sealant. See what happens. I did this during my swap. Wish I knew about that IAC item, DAMN!

The driver's side cyl head sensor is for the gauge (or idiot light)... that's where my mechanical gauge sender is now.

Mine threw that code fixed that right as i was done fixing that my knck sensor went that sucked.ALl related to my stupid computer goin hada get a tranny everything was frying n it... But the Coolant sensor did brake the plastic housing that the connector goes in broke when i did my thermistat.

 

you say it is runnin rich and smells bad, i'm not sayin it couldn't be the CTS but i would also check the O2 sensor.

 

i sure you guys were aware of this, but you know the rotten egg smell is also commonly assosiated with a faulty catalytic convertor. when mine broke, the exhaust at start-up smelled HORRIBLE.
