2000 Saturn sl1
 

I have just bought a 2000 Saturn sl1 with 92000 miles 1.9 sohc when starting the motor cold it will run real ruff and die three to five times when it finely stays running it go about 2200 rpm's for a couple minutes then every thing goes normal what could this be does not do this with warm motor other issue is when i turn on key with cold motor temp gauge comes up to the first mark this should not happen it the gauge or the temp pickup on the motor if pickup where on motor is it located

replace Engine Coolant Temp Sensor (ECTS) (and connector) with brass style replacement. It is a two wire device which threads into the cylinder head on the driver's side. Find the EGR valve and look down.....

Sensor has prob failed and is providing goofy temp info to PCM -- which will in turn screw up your air fuel mix. The gauge is reading high so it seems as though (unless the gauge is defective) the A/F mix may be too lean at cold starts.

Should solve both issues (starting and gauge)

AArrgghhh --- was going to say the same thing, but Derf beat me to it

Thanks a lot that was what the problem was the car starts grate now!!!

Glad to hear
