I just finished working on this 1990 loyale, or so I thought. I am very happy with how the car goes. I cleaned the throttlebody, and used seafoam treatment. I feel the car runs very good and performs well for the 90 horse that it is.

 

My problem is that the engine runs very poorly when cold. I will start it up and it will run a few seconds and die. IT will easily start back up and run a few seconds and die. After it is warmed up it works very well. and happily idles.

 

Any Ideas??

 

Thanks

Colant temp sensor

 

Or IAC

i took my coolant sensor off and cleaned the scale off of it, it ran much better
