2 Is well described in the thread above. Erratic idling and running.
worth your while to read the other threads on this. looks pretty easy to replace on my car.

Did this give you any codes, ?

When this happens it usually possible to start the car either by waiting for the excess fuel to evaporate (at least 30 minutes) or by pushing the gas pedal to the floor while starting. This gives the engine more air and can get rid of excess fuel if the condition is not hopeless.

However...I have replaced, several other sensors...not inccluding these and still have NO codes, but the car runs horrible....hardly back out of the garage but runs. when parked...

Yes, the codes it spits out are:
-11-Crank Angle sensor or circuit
-12-Starter switch or circuit
-13-Cam Position sensor or circuit
-21-Coolant Temperature sensor or circuit
-42-Idle swich or circuit

If you want to test it in the car: Let the car sit long enough to cool completely. Overnight would be best. Measure the ambient temperature. Take a resistance measurement of the sensor. Reconnect the sensor and warm the car up until the both radiator hoses are warm along their entire length. That should put your temp fairly close to the thermostat temperature. Shut it off and take another reading.

if the sensor was any good, it would make the car run differently if unplugged ?
Good logic if you want my opinion. :wave:

I tested the old one for ohm's and got nothing, tested the new one and the ohm's would lower the hotter it got
THANKS EVERYBODY FOR ALL YOUR AWESOME INPUT!!!
