HELP with Codes

I did that paper clip test and it came back with

12 , 15 , 34 somebody please help me with this..


I have a 3.1 Euro Lumina, been having wierd problems, when i let the car sit overnight, i start it up i drive it for about 5 mins NO problems, drives like a champ, well, when i run it for a minute it has this hesistation until i get in the upper rpms, i mean a bad jearking, and then a few clicks that sounds like under my dash and then at about 2,500 rpms its ok as long as i keep it up there.. AND then when i get to a stop sign is wants to stall and the idle in park is just fluctuating almost dying after it warms up

15 is coolant temp sensor voltage reads below -38 degrees for more than 20 seconds so that may be bad, needs a full scan to look at temp reading. 34 is map sensor voltage too low see if you have good vacuum to map

Well my problem is half way fixed.. Everything is idling ok, BUT now my fans aren't comming on my coolant temp sensor is new and my relays work, even if i unplug the coolant temp sensor both fans instantly come on. I'm so confused, i think when i turn my car into the ON position i even hear the relays click, and one time the fan even rotated once..

I check the vaccuum to the MAP and its good, i also changed the MAP sensor itself.
I changed the Coolant Temp Sensor, and now my car isn't having the stuttering or idle problems anymore.

The fans won't come on until temp nears 230 unless you turn the A/C on.

Fans are only supposed to run on demand. If they ran all the time before, that was symptomatic of the sensor problem...

Oops...sorry rich, didn't see you there.:lol:

no prob Jeff, we both got him covered.
