Engine Mechanical problem
2002 Saturn SC1 4 cyl Front Wheel Drive Automatic 11700k miles

put my scanner on car n got code p0410 secondary air injection system. Not sure what this means n chev can only tell me to bring car in to them. Once in awhile service engine light will come on n sometimes car has hard time starting or will need gas pettal pushed to start. Sometimes starts rough but overall not bad. Engine seems to use oil but not leaking. Not sure what is all related or where to start. Thanks for any info!
Do you

Let's start with ur u have to hold ur foot to the floor to start sounds like a bad coolant temp sensor there. That's screwed into the head below where ur upper hose goes on. It has two wires going to it a yellow wire and a black wire. Make sure u check the connector if it's corroded u need to replace it. Also don't take the sensor out untill the engine is cold u will loose some coolant. Make sure u get a brass tipped one the plastic tipped ones crack there under 20. Let me know what u find.
Was this
